This controller, while it is good for some games (Rocket League is what i mainly use it for), It is not a FPS controller, You will not have a fun time playing any games like Siege (Don't use a controller on this game anyway It is very obvious if you are)
or CS:GO. The controller is good for games that don't require fast mouse movements, but it does work pretty good on like SOMA, Amnesia, RTS games etc. for giggles I did play ARMA and PUBG with it, while it does work, aiming was nice, but looking around was almost impossible. It really just needs 1 (ONE) more joystick, if this controller had a dual stick it would easily be my perferred controller, the battery life is great, the cute sounds it makes you can customize, its a good general controller. I'd buy a V2 steam controller if it had twin sticks, maybe some LED lights under the grips or somwhere, to add some eye flavour to it.
