Very happy with these buttons, they feel great, and really make my Zelda build pop imo. I wish they would make shoulder buttons like these, and the sides as well. Would really enhance the overall esthetics of the GBA

They look great and have a nice clicky feel. After sharing with a friend, they pointed out the buttons get warm from your hands. That's a little weird but it's not a deal breaker for me.

The buttons look great! However, they are very heavy. I had an issue where they were weighing down the pads causing the gameboy to register unwanted button presses, but after a fresh set I’ve had no issues. So I’d recommend ordering fresh button pads with these.
