What I have here is a Flip Grip. This neat little invention allows you to play your Switch in vertical mode. This is awesome for many of the shooters and pinball games. I jumped on it the instant I saw it on Kickstarter. I recommend you head over to Fangamer to check it out.
The Switch fits in very securely and locks into place. You then slide the joycons onto either side of the bracket. I worried that it might feel a little off balance in the hand but that isn’t the case. It feels really comfortable and can stand up to long sessions. Actually using it I set my highest score on the Medevial Madness table in Pinball FX.
