The simplest charging system for the Switch Pro controller. I tried the docking station, which required turning the controller upside down to connect. Couldn't get the site line to see which direction to go. I was ready to throw the controller across the room every time I tried to charge. This charging box makes the connection process painless even in the dark. I have a silicone grip on my gamepad. The key is placed inside and the connection is seamless. You can connect as many blocks together as you like. The battery lasts all day and charges quickly. The indicator light is not bright, but indicates that the controller is charging. I can turn off my entertainment system, toss the controller onto the charger, and go to bed without turning on bright lights or my pulse racing in frustration. Definitely worth it.
