The buttons look and feel great. Not sure if they're all like this, but mine came with the sprue attached, so there was a little cleanup required, but nothing major. The included membranes give them a very snappy feel without being clicky. The hard start and select buttons are a welcome addition that adds a polished feel to my build. At first I was wary about paying 15 bucks for buttons, but overall I'd say they provide a premium experience to warrant the price tag. I would recommend these to anyone.

This buttons are great quality feeling and durable too, but you need to use the metal prongs from another L+R set, and they can be difficult to extract from the old set and even harder to install. I’m happy how they turned out in the end and would recommend these buttons with that caveat. Hopefully they will come with metal prongs pre installed in the future.

I'll keep this short & sweet.....
These buttons are really nice. Feel great and love that it has the hard start and select buttons included as well as the power switch and custom membranes. They look awesome

So nice to stare at lol super easy to install !!

They feel very high quality and fit my Gameboy nicely. It was a good purchase and made my gameboy look great!

Yes, they are expensive for painted plastic, but they look amazing. I also love the Start and Select buttons being plastic pieces instead of the normal rubber.
They will look blue until you look at them at an angle, then they are purple.

The only issue is the L and R buttons - they did not want to go in as easily as other button sets, and now the lightest touch can make my L button register a press. (RetroSix Shell)
If I am able to find out why this is happening I'll update this review. But I didn't see any excess plastic or junk material that would cause this to happen on accident, the paint and whatever coating is on there to seal it may be making them larger than normal.

Even with this issue, this is my favorite GBA at the moment.
