I’ve been using this controller to play call of duty mobile. It works really well! Connection to my iPhone 15 was quick. Only snag I had was that it connects via Bluetooth to 2 different names. You can’t just connect to one or the other. It has to be both. Once I got past that it was a breeze. I’m excited to connect it to the switch and try Fortnite with this controller. If your used to Xbox controllers you won’t have any issues using this.

The GameSir G8+ has a great quality build from its buttons and triggers down to even the HD rumble. It’s very easy to set up and switch between different devices/modes (ex. From nintendo switch to xbox mode). It has a wide range of compatibility being able to connect to PC, IOS, and Android to name the main ones. Overall great product!

I use the control for my Nintendo switch. The controller fits perfectly in my hands, very comfortable to maneuver. It was also very easy to connect via bluetooth and good battery life. Overall a good buy, I would recommend it.
