Product is too complicated to use,
For ios user it does not support many versions,
The app provided by the GameSir itself has very bad UI and not user friendly.
You only get to use it with limited game available in the app.
For pubg user in India, we all know pubg global is banned in India so if you want to use it with Pubg kr or BGMI then it doesn't have these games inbuilt.
And all the user tutorials are 1-2 years old for older products, and there is no direct assistance from GameSir to resolve your problem.
For Android user you required Mapping adapter which is also outdated, I got one with box but not working so Be aware before buying this you are completely helpless if product not work properly
