This controller does not work at all

If using the device clip, the controller does tend to fall back if your phone is too heavy.

Now the failures... the whole controller does feel a little flimsy while holding due to the cheap, extremely light in weight, entirely plasic body and the r1&2 and l1&2 stick almost every time clicked(at least mine do)

If you want this controller to emulate old nes/snes/sega/ps1 on your phone, specifically platformers/adventure that require heavy D-Pad use, I think you should find a controller that has a better D-Pad
