I purchased two of these screens. One, I had installed on a stock Game Gear, replacing a worn, scratched up, screen, and it looks great. It defiantly looks a little better than the regular plastic screen cover, as is adds a little more clarity to the, cloudy, Game Gear display.
The second I had installed on a McWill modded Game Gear, and this one looks even better. With scan-lines enabled, the pixels look super crispy.
Both look clear, and where easy to apply. I would suggest adding just a bit more adhesive, to help them fit more secure, but other than that, the quality is superb.
