Ratings and reviews

Fantastic app. I have read some of the other reviews already, and maybe my experience is holly different, was having problems with my controller, tried everything (except taking it apart) this app fixed that entirely, helped a great deal, can change the colours, brightness, and other stuff which seems Allright and doesn't seem broken, the app does have an affect on the device and works fine for me. Great nintendo switch device and great app to compliment my glowy in the dark controller. Love it

Hello! I have an Aolion K20 TMR joystick. I used to have an issue where, after turning on my computer for the first time, the joystick would go to sleep and fail to reconnect. This app helped me update the firmware from version 4.08 to 4.15. The joystick was recognized immediately in the app without any problems. Now, after the update, everything works perfectly. Everything’s great — thank you so much!

app work just fine, however the controller suffers from lag when trying to activate amiibo, not working in legend of zelda botw. works better in totk with amiibo working but takes a couple of goes on controller. needs a firmware update for controller greater than current 1.80. controller still waiting for a firmware fix march 2026.
