Kinvoca Joypad Controller for Nintendo Switch review - Don’t even bother - Android

The only real advantage these Joy-Con knock-offs have over real Joy-Con is that you can individually charge each one. However, that charging is via Micro-USB, which the Switch doesn't support.

Outside of that, these are just poorly-made cash-grabs. At this price, there are literally dozens of other products you could buy that would at the very least give you more features and better build quality. These should be a last resort only.
