Unsatisfied
The quality is low. The protectors are easily bend and scratched. Too thin. Easily leaving marks after playing my DSi just a few times.

Fairly low quality.
Low quality material with inexact cutting/sizing and flimsy packaging. Putting it on was tricky and one of mine was slightly magnetized and ruined itself by sticking to itself. I could use the back-up it comes with, but still wasn't entirely happy compared to other screen protectors I've used.
