The glass I used has a small defect along one side where the adhesive looks funky. Don't really notice it during play. Otherwise looks really nice.
I bought this for a Gameboy Zero build. The glass screen cover really completes the build. The adhesive that is preapplied to the glass works well for applying to the gameboy. A great product that I would buy again without hesitation for any future GBZ builds.
Worked perfectly for my PiZero build, and is strong and built with quality.
