Stay away from DInput (DirectInput) only controllers as much as possible if you also have the intention to use it on Windows. Unfortunately, many of those cheaper Chinese telescopic or clip-on phone/tablet controllers only support DInput and not XInput, which will make it a right pain to get to work in most situations. It's not something that's clearly stated anywhere usually either, so keep that in mind.

However, if you do happen to find a Chinese controller, and there are some okay ones out there, that unfortunately only has DInput; there exists a fantastic tool to emulate XInput called XOutput that I would highly recommend!
