Review on GreenWhite Charging Dock for Nintendo Switch: Convenient Charging Station for Joy Cons & Pro Controllers with LED Indicator by Beth Finlinson

Not very convenient to use. In particular, the chargers on the left for the joysticks didn't have good connections, so I had to squeeze and wiggle the joycons to try and get them to charge. The same applies to ports for professional controllers. I threw this product away after a few months because the joycon, which I had been charging for a few days, showed a low battery level after plugging it in - it sat in the dock and couldn't draw power while the light indicated that it was fully charged is. I wouldn't recommend it unless you're desperate as the price is pretty low.
