content: I should have read more reviews before I bought this, because after a few weeks on my keychain, the end broke off cleanly. The unit still works, so I'm going to attempt to superglue it on, but I'm disappointed.For something that claims to be washer and dryer "safe", it's very fragile. The hole for the keychain ring should extend through the PCB, not the soft white plastic cover. I'm glad I didn't lose my data, but I'm not sure I'll trust this with anything important from here on.
