(16) Ultra Pro Magnum" Roller Rockers - Stud Mount - GM LS3/L99/L76/Rectangle Port Heads
As LS engines continue to grow in popularity, COMP Cams® has expanded its line of rocker arms to build components specific to LS applications. New Ultra Pro Magnum" Rockers are made from investment-cast 8650 chromemoly steel, utilize upgraded trunnions and needle bearings over stock and are stronger, stiffer and more durable than the stock parts. They also feature a 1.8 ratio (compared to the stock rockers 1.7) and utilize a roller tip instead of a slider. The higher ratio and increased stiffness make these rockers a great option for increasing lift without changing cams. This increased stiffness, along with the upgraded trunnion package and roller wheel, also makes them a perfect choice when running aftermarket valve springs. The rockers are available in a bolt-down design that uses stock rocker stands and in a stud-mount option for customers looking for an adjustable valve train. The stud-mount version is perfect for individuals running mechanical lifters as well. COMP Cams® LS Ultra Pro Mangum" Rockers Arms are available for LS1, LS2, LS3, LS6 and LS-based truck engines and come in individual sets or kits featuring studs and guide plates. Kits do not include pushrods, but they are available separately.

10/10 product. Best on the market.
Color: Stainless Steel, Color: Stainless Steel
This thing is bomb. I can confirm that it is legit and cooks way more effectively than a lot of of the other options, especially for oven air fryers, but even against basket air fryers we originally got a ninja dual basket, vertical stacked air fryer and had to return it because of a weird whining noise. I’m so glad we did because this thing has been killer. The thermometer option for reverse searing stakes makes it so easy to get it to the exact temperature and then sear it for 90 seconds on each side. even in general regular air frying stuff is great in here. Pretty easy to clean everything fits in the dishwasher, but also it’s easy to clean with a sponge. It’s pretty big and can fit a lot of things and the best part is The front end is very user-friendly. My fiancé had a hard time figuring out working the ninja, she found this to be much more intuitive to work with

Great performance, versatile, quiet, reasonably priced.
Color: Stainless Steel
Terrific air fryer / oven. I bought it to replace my smaller air fryer. It does that, and more. Since I only have one oven in my kitchen, this serves as a backup. Large enough to many things. Air Fry / Roast / Bake etc. The wifi connectivity is helpful -- lets me set up and run a task, and lets me know when done. The included and integrated wireless temperature probe is great. Set up your roast and forget it. Get a notification when done. It is also quiet! Great buy.

Color me impressed!
Color: Stainless Steel
Color me impressed! So far I really like this Typhur Sync oven. My first test was a frozen pizza. Unfortunately, it was overcooked. I really can't remember at this moment the exact temperature/time settings I used. (Probably used the box directions.) However, next time I'm going to just select the pizza setting on the oven and trust it. This is a convection oven, so I shouldn't have used the box directions. My next test was a big one. I cooked a 5.6 pound rib roast for Christmas. I selected “beef”, then “medium well”, then hit start. After the preheat was completed, I put the roast in the oven. Of course, before putting it in the oven I inserted the wireless temperature probe. I had taken the roast out of the fridge to let it get to room temperature an hour or so earlier. The probe said its internal temperature was 56 degrees, and the target temperature would be 140 degrees. I looked at other ovens as well, but selected this Typhur for its wireless probe and phone app that would track the oven progress and alert me when it was completed. The oven is downstairs, and this app would save me much stair work. It worked great! Love the little app. I checked the app from time to time for cooking progress, and it would tell me its current internal temperature and the target temperature. Also told me the time to completion. Amazing. It “dinged” my phone when the oven was done. I went downstairs and removed the roast. It looked fantastic. Of course while sitting on the counter top, the roast continued to cook internally while we were getting everything else set up on the dining table, thereby making it more like “well done” when we were finally ready to eat. After slicing it, the meat looked great. Not as pink as I wanted, but that was due to the “internal cooking” it did. I think next time, I'm selecting “medium”. Then it might be more like “medium well” when we're ready to eat. Also, did I mention that the cook time was just a little over 90 minutes? Couldn't believe how fast it cooked. My next test was cooking a pork tenderloin “medium well”. It took 33 minutes, and turned out great. Again, I'm very happy with this purchase. Back story... Years ago we remodeled our kitchen in a previous house, and not wanting to discard a perfectly good wall oven, I built a box for it and kept the oven in our garage to act as our second oven. Well, after 26 years it finally started failing. (Couldn't blame it for all the hot summer and cold winter cycles it went through.) Repair cost would be unreasonably high, even if the parts were available. Looking to replace it would cost anywhere between $450 (for a “no name” oven) and $1000 or more (for a “known brand” oven). I then saw these counter top ovens. After some study, I gambled and selected this Typhur Sync for $230 (also a “no name” brand to me at the time). Glad I did.

Good little oven
Color: Stainless Steel
Delivery was prompt. Wasn’t sure what to expect on the oven but the controls were fairly intuitive and have used several of the settings. Performs well on everything that we’ve used it for. The instructions are basic but adequate to get you cooking. The size was a little larger than anticipated, it is deeper and takes up more counterspace but you can cook a chicken in it! Looks great sitting on the counter. Not too industrial and the buttons and knobs make changing settings easy.

We love it!
Color: Stainless Steel, Color: Stainless Steel
Simply said, it’s great!
My wife absolutely loves this little oven. It has a bunch of options to choose from for cooking. You can use it as an air fryer, oven, you can cook perfect crispy wings, as well as a nice piece of steak with the included thermometer.
Since it’s very little compared to the regular house stove, its much easier and quicker to clean it.
It’s a must have for any home!
