I had my doubts about these glass lenses, but they are very thin, the thickness of the glass is perfect, it does not go beyond the case and it fits perfectly, your gameboy really looks incredible when you make the change, it is easy to clean, the background color is Black, perhaps the only thing I noticed different compared to the original, but it looks very good to replace those scratched plastic glass lenses. What I noticed was that the letter C and E at the end of Advance may be a little strange. But you don't appreciate it unless you're very observant. I leave some comparison photos.

Looks really good!

This was perfect for my new modded gba. I really like how the glass looks paired with an ips screen would recommend. The adhesive is also good too it doesn’t come off and seals great so now dust can enter.

Very nice looking lens, I like the holographic sheen it has

Dropped in OEM shell well but had some issues with a third party - I don't fault the lens for this though.

Looks nice and has held up well for a few months of regular play now

Fits great and looks good too!
