Overall, I had little confidence in this product's ability to protect my games. First of all, the plastic is way too thin and flexible, making me nervous that the game might warp or crack. This also made the cases pop open, exposing the disc. The seal just doesn't seem very secure at all.
I also questioned the size. It's the size of a game disc, and so thin and small that it could easily slip somewhere and get lost. Honestly, if I was going to bring one game with me, which seems to be the aim of these cases, I would feel a lot safer just carrying it in the box itself.
