When fully assembled its got a wider grip to it making it a little nicer to hold with the Nintendo JoyCons. The charge port (USB-C Type) is at the top of the controller which is good if you intend to play while charging your JoyCons. I didn't use any of the other provided accessories which were unnecessary for me personally but I love this product.
The build quality is good and the handle grips feel large and comfortable in the hand. It's a great thing to have when you only have JoyCons and don't want to attach the JoyCons to the switch to charge leaving you unable to game. I have a Switch ProController as a backup just in case. Please note a charging cable is not included with this product so be advised. All in all if you're looking for a solid third party JoyCon controller charge grip look no further this is a pretty nice contender to the Nintendo version.
