This product looks good and beautiful, but it doesn't work properly. See below for a detailed review. Appearance (3/5): You are definitely unique. Not an elegant look, but you can't mistake them for anything, when they appear you can find them. Feel (4/5): They feel fantastic in the Pro Controller. They don't slip off your finger and the grooves give you a good feel for thumb placement. Fit and usability (1/5): This is where the problem lies. This part is the main part of the review as it consists of two parts. The main thing is that they are turned on on the controller, although they just don't stay on. After trying it on several controllers, they don't work for all. They won't fit on a Lite switch or switches that are too big. And the pro controller comes in different sizes, but the one I use seems to fit the best, although they still pop up. Regarding the main pro controller. The short one keeps slipping and the middle one hangs mostly, but when pressed it turns into a ball.
