Benchmark: While the rest of the industry has been asleep at the wheel in this category; Morimoto was hard at work developing the successor to the incredible 2Stroke 3.0 LED bulbs. The 4.0 re-creates the original beam pattern from your optics effectively by doing more with less. They will put more light on the road for you as the driver, while creating less glare for oncoming traffic compared to any other LED bulb on the market today. While LED bulbs still aren't DOT approved for use in headlights in the states-- foreign markets and fog light users can enjoy the best plug n play LED bulb to date. The 2Stroke 4.0. (Featuring technology patented by Morimoto) Superior Beam Quality: The advanced Aluminum Nitride Ceramic circuit board in the center of the 2S4 sets allows the bulbs to produce the most precise beam pattern possible, with its 1.45mm surface-emission interval. For reference, the tungsten filament in a halogen bulb is 1.4mm, and the previous record for an LED bulb was 2.0mm, set by the outgoing 2Stroke 3.0 bulb! Using the industry-first ceramic PCB, we have eliminated the need for the dielectric layer and a separate thermal element, which, in combination with the Osram Oslon HJL531.TE LED chips makes for unmatched performance when used in all reflector and projector-based headlights designed for halogen bulbs. H11 Tension Spring: The base of the of the 2Stroke 4.0 H11/H9 bulbs has an integrated tension spring that pushes the entire bulb base downward with 5nm of force, resulting in a bulb that's been properly seated according to the needs of optics. The complexity and cost that went into developing these parts alone was a significant investment, but one we had to make in our continuous pursuit of perfection. We would be impressed if you could find another brand who cares enough to make this kind of investment on this often-overlooked feature. Optimized focal length: Each size in the 2Stroke 4.0 lineup has been painstakingly optimized for proper output in its designated application. The critical reference distance has been calculated based on the geometry of the bulb base and the footprint of the Osram HJL531 emitter. To ensure consistency, special tools were designed to quality-control the accuracy of each bulb as it comes off the production line. Most other LED light bulbs on the market use a 'set it and forget it' reference distance across all sizes in the series, making for sub-optimal focus in most applications-- not the case with the 2Stroke series of bulbs. 360 degrees of Rotation: Since no single standard exists across different headlight and fog lights, all bulbs in the 2Stroke 4.0 range are fully adjustable so that you can dial-in the position of the LED chips so that they sit perfectly at the 3 and 9-o-clock positions. On the previous gen bulbs, the gears on the base were prone to slipping when locking it into your headlight, but the new system is immune to that. In summary, setting up the alignment of your bulbs is now easier than ever! Thermal management: The 2Stroke 4.0 uses an upgraded version of the patented system we first employed on the 3.0 bulbs. This unique cooling system uses a 12,000-rpm dual-layer fan to suck cool air into the body of the bulb and blow warm air out, back into the housing. On the intake side, cold air is sucked in past the sidewall of the PCB to exchange heat and is blown out the opposite side of the bulb. This effectively cools the bulb while warming the ambient temperature inside of the housing, increasing resistance to snow/ice buildup on the lens during the winter months. With even more static pressure than the previous version; the cooling system on the 2Stroke 4.0 maximizes longevity of the bulb, while serving up a bad-weather benefit not found elsewhere. Unique Drive Logic: The LED drivers are programmed to start up at a conservative 18W, and then ramp-up in power over the first 15 minutes before stabilizing at 22.5W. Unlike every other bulb in the aftermarket which lose output intensity over the first 15 minutes of runtime (as the system heat-soaks), the performance from the 2Stroke 4.0 remains impressive from the moment you pull out of the driveway till the moment you park the car. Lifetime Warranty: The Morimoto 2Stroke 4.0 bulbs are produced using the latest OE-grade materials, electronics, and LEDs for the automotive industry. The conservative LED drive rates and highly effective thermal management systems make for low operating temperatures. All of this adds up to a bulb that is designed to last, and that's why they are backed with an industry-leading lifetime warranty.What's Included:

Works for what I need it for
Color: Black
I've been using this type of keyboard for years. I remember back in the late 1990/early 2000s, I was working as a medical transcriptionist and my supervisor at the time was using a "curved" white Microsoft Natural Elite keyboard. I was still using the typical, out-of-the-box, straight keyboard. She gave me hers to try out for a while. At first, I HATED it. My typing speed was terrible, I was pressing every wrong key, etc. But after I got used to it, I realized there was no way I could ever go back to a straight keyboard. Now, all of these years later I'm still working as a medical transcriptionist and have graduated up to the Microsoft 4000. I still have problems using a straight keyboard - in fact, when I'm using my laptop for work I cannot use the laptop keyboard and have to hook up my own keyboard in order to transcribe.
Compared to all of the other "ergo" keyboards out there that I have tried (and I have tried quite a few), this is the best I've found. Now, I have never tried the Kinesis which I hear once you try and actually get used to you will never go back to anything else ever again and that it's the "best of the best." I have thought about trying one of those out, but I just cannot justify the cost. Perhaps if I was suffering from more carpal tunnel symptoms, more wrist pain, etc., I would give it a try, but as of now the Microsoft 4000 works for what I need it for. I am pairing it with an Anker wireless mouse, which took me a while to get used to but now I couldn't function without it! My sister was visiting me a few months ago and she was having a terrible time using my keyboard and mouse just to function on the internet and I then realized how somebody who isn't used to it feels. As I mentioned above, I've been using one of these "curved" split keyboards for nearly 20 years now, so I'm definitely used to it. With this keyboard, my hands feel like they are at a more natural position compared to a regular standard keyboard where they feel to be unnaturally squished close together.
When I worked in-house at a local clinic (I currently work from home), we had occupational therapists come over to evaluate our work stations, etc. I was told I have hyperreflexia and that the best position for this keyboard was to keep the lower bottom "riser" attached and to keep the top legs folded up so that my hands are sloping down from my wrist placement. That is the best position for me, but others may be different.
As I mentioned before, I have used this brand of keyboard for years, though I need replacements every six months or so as I am definitely NOT easy on my keyboards!! I always keep a spare one around which is good as the other day my Diet Coke spilled all over the one I was using. I thought I caught it early enough and got it all drained out, but nope, it was (and still remains) dead. So the spare I keep around does come in handy!!
All in all, this is a great keyboard for those of us who type on a regular basis. My only complaint (and this is not with EVERY Microsoft 4000 I've purchased, only a few) is that there are times when the space bar is a bit sticky. I pound the keys so hard while I'm typing that I generally don't notice this, but I have had a few that I have noticed it on. Otherwise, all keys seem to depress well. The letters on the "common" keys do wear off around four or five months, but that is something I could care less about as I don't ever look at my keyboard when I'm transcribing (though those that attempt to use my keyboard have commented on it)!!

Good keyboard but it takes time to adjust.
Color: Black, Color: Black
I had a prior version of this keyboard (the Microsoft Natural Ergonomic Keyboard 3000) for my office PC. It did admirably, but after a year or so, my wrists were starting to hurt IN SPITE OF the ergonomics helping. This one is better rated. So far, it has helped, but it took at least a week of use just for my hands to BEGIN to get used to the differences. I'd do a pro/con list, but I'm not sure there are any "cons" as compared to "issues to expect" if you buy this keyboard.
1. Expect a steep learning curve to get used to the layout. The "bend" in this keyboard is significant, and it will take time for your fingers to get used to hitting the right keys on a consistent basis. Give it one or two weeks of regular use before deciding if you like it or not. You can't know in a couple of days if it's helping you because you do need to re-learn your hand placement and fingering to some degree.
2. There is a physical break in the left and right hand keys. This "no man's land" means you need to unlearn using the wrong hand for the wrong keys because you will either miskey or just hit nothing when you go to use your right hand to it the G key (or a similar situation). Likewise, some of the keys have an odd shape that takes getting used to. I had considerable issue getting used to hitting V and B correctly. Again, this is all about relearning how to keyboard properly. My best tip is to avoid looking at the keyboard while typing. For me, looking at the keyboard made it harder compared to just backspacing and repeating until I got it right. Passwords are about the only thing where I still watch what keys I strike.
3. This keyboard is wider and "taller" than most. If you use a keyboard tray, clearing it might pose and issue (see next point below). You will likely have less room for your mouse as well, but I found it something I could live with.
4. The keyboard has three (maybe four) resting positions. There's a removable front skirt that elevates the front. There are the standard rear folding supports to elevate the rear. So, that's resting flat (none), rear elevated, front elevated, and both elevated. Lying flat, the keyboard works fine with my keyboard tray. Set the way I find it's most comfortable for me, I can only push the tray in halfway before the keyboard hits the desk. This isn't a deal breaker for me, so I'll live with it. You keyboard tray may need to allow at least 3 inches of vertical clearance to not have an issue with this keyboard.
I was divided on four or five stars, but since I need this more extreme curve to deal with wrist pain, it's not the product's fault, so I won't hold the awkwardness of it against the designers. It does what it's designed to do for a good reason. That comes with a trade off.

I was glad I bought it until four or five months later...
Color: Black
I am now about a week and a half into using this keyboard. It is the first time I have used an ergonomic split keyboard. I am a medical transcriptionist and type for a living. At first I found it awkward, I kept reaching too far for some keys, and it seemed that I was always missing the right-sided home row by one key. Now I find that I'm not thinking about the keyboard at all, which means it is working well for me. I find the key "touch" to be a little on the firm side, which means that I occasionally miss a letter because I didn't push hard enough, but I think over time I will adjust to that, too. This keyboard does not "click" when you type, which means it is generally quiet. Personally, I prefer the clicking, but for work, I wear a headset and don't hear the keyboard at all, so this is not an issue. Of course, with the need to press the keys harder, there is more thumping than I think I would normally hear when I type. As far as the alignment, it seems excellent. I have rheumatoid arthritis, which is well controlled, but I still have some stiffness and loss of range of motion in my fingers and wrists, and the angles of the keyboard seem to be perfect for me, and I don't feel as much strain as I used to in my wrists after working all day. There is one thing I wish was included, and that is a lighted keyboard. I have never had one, but I have worn the letters off the keys of several keyboards, plus it would just be helpful to be able to see the keys more easily for those times when you don't have bright light or so your eyes don't have to adjust to dim lighting after staring at your bright monitor screen for a long period of time. After less than two weeks, I can already see shiny spots on the space bar and some of the most-used keys, so I know the letters will start wearing off soon. Not a big deal, but a lighted keyboard would be a really nice feature, perhaps an option that could be offered in the future. If you are considering this type of keyboard, I think it is worth the minor aggravation of needing some time to get used to it. My impression is that my hands and wrists will be thankful I made this purchase. UPDATE JULY 22, 2015: The keyboard started acting strangely yesterday morning, some keys not working at all, some keys creating the wrong letter or digit, and the period key seemed to be stuck. I tried to file a claim using the extended warranty, but because it was still under the manufacturer's warranty, they told me to contact Microsoft, and they gave me the wrong phone number for Microsoft. Microsoft wanted the keyboard to be shipped back to them in California, and they would send a replacement AFTER they received this one. I use the keyboard for work, and I don't have a week or more to wait for a replacement. I asked for my money back, which they agreed to do, BUT they then sent me on a wild goose chase trying to make that happen. It seemed that no one with Microsoft had any idea of how to help me and they didn't seem interested at all in helping me, although one person I spoke to at one of the wrong numbers I was given was very kind and helpful in spite of my anger and frustration (thanks, Sachin!), but he couldn't help me either, and he said I needed to contact Amazon. This was definitely NOT Amazon's problem, but you know what? They made it right. No arguments, no questions, no lengthy explanations, no making me feel like I was trying to take advantage of them. I asked for their help, and they apologized for the troubles I had experienced and sent a new keyboard. I have heard people complain about Amazon, but as far as I'm concerned, they are AWESOME. Microsoft and Square Trade Warranties not so much. This keyboard should have lasted longer than a few months, and Microsoft's customer service was horrible when I needed help, so when I have to purchase another keyboard, I probably won't buy another Microsoft product. That said, I have been very happy with the layout of the keyboard and I wish it hadn't malfunctioned so quickly.

Wonderful keyboard, VERYuseful programmable buttons aplenty. Only problem: Intermittent connectivity problem with wireless unit.
Color: Black
I really love this keyboard, having used "ergonomic" keyboards for a great many years now, and using nothing else.
The design is really nice, with the split keyboard being an increasingly rare thing to find these days. Almost no models made by anyone offer such a design, but even if there was more competition of this type, I still think this keyboard is great.
The programmable buttons (MANY of them) are a huge plus. You can program most of them to do all kinds of things, including opening often-used documents or websites for you, or running macros you write.
The buttons that are intended for specific purposes, though, are so well thought-out that I leave most of the button assignments as they are. For example, the buttons dedicated for increasing, decreasing, or muting the speaker/headphone volume are VERY useful very often. And the calculator button also gets a lot of use. Others are the same: very well-thought-out standard assignments doing things I do often (and that presumably most people do often), and once you get used to the fact that now you have a button that does what you want (at first, you'll do it the slower way requiring many more button presses &/or mouse pointer clicks), this keyboards full functionality really shines through for you, and you can't imagine how you could use anything else!
The removable palm rest is another great feature, by the way. Since I use this on my lap, and the bottom of that thing isn't comfortable at all that way, I'm very happy it comes off. And it goes on and off very quickly and easily, in case you want to move it back and forth between a non-organic surface and your lap.
The only problem I have with this keyboard in its wireless version (I have both cabled and wireless ones) is that with many positions I get in, even when the keyboard is VERY close to the receiver plugged into the USB jack on the front of my computer, it won't work at all many times. But when the keyboard is in other positions that have NO line of sight to the receiver, it works fine. It's very particular that way, with some orientations that seem like they'd make for very easy connectivity being impossible to use, while other orientations/distances that seem like they wouldn't work work just fine. Go figure. But once you learn its oddities, you can work around that by moving the keyboard and/or the receiver plugged into the computer so that it works. I do still find it annoying that it seems like the most comfortable positions I want to be in often seem impossible to make work, even with very close proximity. Using the wired version, of course, removes this problem entirely. But I think that the connectivity of the wireless version should not be so touchy and idiosyncratic, and would describe it as a "design flaw." I would have to say that, overall, this isn't enough to warrant deducting a star, though.
Overall, though, I'd say it's a great keyboard, and highly recommend it.

Good all around design with plenty of functionality; best design especially for this price. Very comfortable ergonomics.
Color: Black
The ergonomics of this keyboard are very helpful. I've purchased this same keyboard many times over the years (they wear out). It takes some getting used to, but I love it. It's a more natural position. I'd like it better if there was more space between the two sections of keys, but I would assume they were trying to keep the footprint similar to a regular keyboard for space reasons.
This made a big difference in my neck and shoulder pain and I don't experience any wrist pain like I do when using other keyboards.
I don't know if they still make the wireless version, but I can't recommend that as it wears out even faster than the wired keyboard. And that leads me to the one real drawback - they wear out too quickly. Usually the letters on the keys wear off first, which usually isn't a big issue since I don't look at the keyboard much, but when I do, it's a pain that the keys no longer show the some of the letters. The keys themselves begin to wear out. It seems to me it happens faster than it did years ago. They used to last a few years before they keys stopped responding well (nothing happens when you hit the key and then suddenly you get a jumbled mess), but in recent years, it seems like I need a new keyboard every two years. I suppose that's one way to make sure your product continues to sell. Also, initially the keys are fairly quiet, but it doesn't take long before they're quite noisy.
In comparison to other ergonomic keyboards, this one has the best design in the lower price range. Others with better designs run into the hundreds. I highly recommend this keyboard.
