This controller works great for COD Mobile. Makes the game more enjoyable. Aim faster, throw grenades with a single pull of the trigger. The trigger response is pretty good. It takes some getting used to, but your game will improve. The fan seems to help keep my phone cool which is a plus. Great price for a solid controller. Update: I still like this controller, but the flat piece of metal that connects to the actuator breaks after a while, as do the little springs. I bought a second one that still works, using parts from the first. It would be nice if they included a few extras from each as a backup. I also used Frankenstein jewelry wire. You do what you have to do to continue your game. In short, it works fine until it works. If you are a hobbyist, you can continue this for a while. Although I still like it
