I like this idea very much. This concept was exactly what I was looking for as I have an extra pair of joysticks for games like Mario Party and Mario Kart where you only use one joystick per person. If you don't have a docking station to charge your controller, you'll need to connect the joystick to the Switch to charge it. If you add this handle to the joycon, you can charge it with a USB-C cable. The grip slides securely over the joycon and really gives the controller a much better grip in your hands. The top trigger buttons are very responsible and comfortable to the touch. HOWEVER, it is a very THIN and LIGHT plastic. It feels cheap and makes the whole joycon look less massive and plasticky. The USB-C ports seem unreliable and questionable, and it is not known if they will work in the long run. On the plus side, 2 USB-C cables are included, which feel nice. I would NOT use them to charge the Switch. But with controller charging it seems normal. Overall for the price it's what you pay for. They make the joycon much more enjoyable when playing individual joycon games.
