Built to Adapt, Engineered to Perform 

Enjoy versatility with no limitations when you tattoo with the FK One Adjust. The FK One Adjust is built to adapt to any style, so you can pursue any project for any client. This patent-pending stroke adjustment technology delivers effortless adaptability, so you can tackle any technique on the fly. Easily adjust your stroke mid-session without ever having to power off your machine. One setup handles everything: no need for swapping machines or cams mid-session. 

Enjoy nonstop, all-day wireless performance with 2 swap-and-go rechargeable batteries. Each FK One Adjust comes with one large battery for up to 6.5 hours of power, and one small battery for up to 5.5 hours (depending on your settings and operating parameters). This machine also gives you a dual-slot charger, so you can always have a battery powering up and ready to go when you need it. 

Get full visibility and control over your performance. The FK One Adjust features an upgraded digital display that gives you a crisp readout of your operating voltage or hertz according to your preference. Why Hertz? Hertz offer a more accurate measurement of your machine’s performance, showing the exact frequency of needle movements per second.  

Trust in the FK standard, knowing the FK One Adjust has an artist-first design. This machine was built with artist input and is specifically designed to handle everything you throw at it day after day, session after session, from first line to final pass. It’s reliable, durable, and built to last, supported by FK’s global service program. 

HOW THE STROKE ADJUSTMENT WORKS

The FK One Adjust features an innovative custom engine that redefines adaptability. A fixed-stroke cam connects to a precision paddle, while a rotating slider adjusts stroke length by moving closer to or farther from the paddle’s center. This design reduces friction and wear, keeping performance consistent session after session.

A first-of-its-kind system built to keep your flow uninterrupted and your performance unmatched.

Almost Perfect
Color: Graphite, Pattern Name: Mouse
If you are looking for a quiet mouse, this is it. I was skeptical about the "ergonomics" but find that it is much more comfortable for me than the more traditional design for left and right clicking. Simple moving seems fine but its weight is a bit excessive for lifting for repositioning in tight spaces. It is difficult to lift without activating the button on the haptic pad, even set to require firm pressure. A bit more contour on the right would solve this nicely to allow lifting the mouse without repositioning your hand. The forward and back buttons may be a bit awkward for some people. I'm slowly adjusting. Actually, each mouse I've owned needed a bit of getting used to. Side scrolling doesn't always work as it seems it would. Frequently, it scrolls vertically like the "normal" scroll wheel depending on the program. Haptic feedback is not a commonly used feature yet, however, Windows will be slowly adding haptic features to later updates from what I've read. I keep the setting on the lowest haptic feedback level and for what it functions on so far seems natural and not intrusive. There are many adjustments and customizations, too many to go into since I haven't played around with most. So far, even with what may seem like a lot of negative thoughts, I love this mouse. It would be five stars if lifting to repositioning in tight spaces was easier.

Dependable, Reliable

As advertised. Logitech, best mouse for your hard-earned cheddar! It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse. So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it! 😉

Hey, it works well. Just plug it in and you are ready to go. Only issue, minor, no light or color coding on back to indicate on or off.

Smooth and ergo nice mouse.
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
I needed this little thing quickly and got it within 2 hours of ordering. It was only an extra five bucks to get it now. Would have burned more than that in fuel. Works exactly as I would have expected. Perfect.

Simple and efficient
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
This is a dandy little item. Easy to use straight out of the box, No fancy bells and whistles.but why should a mouse try to replicate commands that are on the laptop?
