Agreed. I've found this to be almost essential for carrying my DS games. I used to worry about them getting damaged, but they're well protected in this thing.
I'll definitely be taking extra care with it as I can see the inner mechanics of it getting easily damaged.
Good but not the most rugged This is definitely the most compact 6-card case around and the form factor is great. My only issue with it is that the "hinge" parts are a little flimsy and 2 of the tiny nubs that lock games in place have come off. It's still usable, just be nice to it if you get one.
