I really enjoy this app, and the electronics so far, it lets you adjust basically everything on the gun !! The only thing I would recommend is the option to "reset" the errors, cause they stay in the memory even when I log out and log in again. (Update: Error clean log now available, it's awesome!)

Works well, great on the fly tuning. Unless ive overlooked it somewhere, i wish it had magprime. Edit: per developer response i now have magprime activated! Thanks!

The app works really well. The only part which is difficult is the Bluetooth connection which often drops while browsing through the app or when you lock and unlock the phone

The performance of this product is amazing. easy to use and bluetooth connection will no doubt be copied by the other companies in this market. Well done Jefftron.

It's a great mosfet and app but for Android it's super laggy. Once it is up to par for speed I'd give it 5 stars anyday

Easier than gate. To me leviathans are alot better than anything gate makes and easier to access and customize.

Love the app i have 2 replicas that have this brand mosfet and the app is very helpful for teching and trouble shooting without taking stuff apart. 10/10

Only problem i have had is disconnecting when locking and unlocking the phone, apart from that it's brilliant
