Skull & Co. Back Button Enhancement Set for Steam Deck, Handle Grip Pads Improvement Button Protection Kit for Steam Deck - Black, 4pcs

If you like using back buttons (and if you play games that require both the right thumbstick and the main ABXY buttons then you should!), these make the Steam Deck back buttons much easier to press, as they add an angle to them that is aligned with the resting position of your finger. It makes a bit difference - highly recommended. (If you aren't sure why you'd want to use back buttons, just think of any time you take your thumb off the right stick to press a button. If you assign that button to a back button, you no longer have to take your thumb off the stick. Really useful for games where you want to do something while moving, e.g. looking around and jumping at the same time)

considering their simple nature, 4 stick on pieces of rubber/plastic they are surprisingly very effective at what they do, they take advantage of the fact your fingers on the rear buttons wont always be flush but will be slightly angled from the way you hold the deck, these stick on button grips are likewise angled in such a way that your fingers will find better purchase when holding the deck, i was very surprised how well they work, got 2 sets, 1 for lcd and 1 for oled deck, well worth the money even if they are very simple in nature. I have had a similar product in the past and im glad to see this product does not suffer from the same issue as the previous ones i have tried, previous designs made you apply the sticky tape yourself to the button grips, these ones come with tape already applied and are easy to remove unlike several other designs i have tried, they also come with a sheet of many spare sticky pads should you need them. Just remember that the pads are named after the rear buttons and must be applied to the correct buttons, you dont just slap them on anything or they will be misaligned.

Fantastic item 10/10 recommend. My go to company for Switch/Steam Deck accessories
