Very cute. I'm glad I read another reviewer who advises stacking several stickers together for use with a case. Everything worked perfectly, all buttons worked. I ended up using all the stickers the same color. 2 for x and y, 3 for a and b (I have an old system so some of the keys are lightly pressed). The instructions say you don't need to use stickers for the top and bottom buttons + pad, but 1) I would recommend that and 2) with the case, I had to fold them as well. My only complaint is that I prefer the silicone cover on my buttons. However! 1) It's very difficult to make a silicone grip without a burr to hold on to, and 2) the original buttons are plastic anyway. When making future products, they could circumvent this by only using silicone pawprints. If you do, please let me know!
