"Man this thing is great. The app is a little wonky but very solid overall. I haven't tried a Gate Titan to compare but this definitely feels like a top tier mofset with all the possible functionality one could require.
by Zeb N. on 08/16/2021
"This thing is awesome! I love how easy it is to adjust settings with my phone. The trigger response is amazing. The only thing that I wish was different is that you could make it a hair trigger, but the with the way the micro switch is set up is so that it can't have that short of a trigger pull. Nevertheless the trigger pull is still way shorter than your average trigger switch! I would highly recommend this MOSFET to anyone looking to upgrade! I will never go back to a regular trigger switch again!
by Stuart B. on 06/12/2021
"For the price, this is an amazing mosfet. After installing this into my gun the trigger response went from an extremely whiny slow m4, to basically what feels like a dsg. When paired with 13:1 gears and a high torque motor, this thing is a beast. With the small set screw that is included with the trigger it is easy to make the trigger pull next to nothing. And with the precocking turned on the trigger feels amazingly snappy. The bluetooth is also a nice and easy feature.
My only complaint (and it is my fault) is that my semi microswitch broke. I forgot that you have to file down he edges of your selector plate to prevent this. So I only have a full auto. But with the bluetooth I can program it to do semi to comply with field rules.
