The plastic for the memory stick broke and now it's missing a piece of the front part. Keep in mind, it is adult owned and only ever went into a psp. Therefore, it wasn't being abused or handled improperly.
Also, after the plastic broke, I started noticing random freezes in data transfer.
I am visually able to see this issue because I use the memory stick for playing backup games on my psp. The game will randomly hang multiple times throughout my time playing. I didn't have this issue before the break in the plastic.
Minus 2 stars for each problem.
