So far I've played a few games and it's great I have a galaxy S8 the reasons I bought this one,
1. It does not interfere with the volume or Bixby button unlike other ones have.
2. Its triggers are closer to the screen so it doesnt take much pull on the trigger to shoot or aim.
3. It holds on to the phone very tightly.
4. It has a good feel in the hands and I have bigger hands.
5. The buttons dont bother me on the screen.
