This is a solid piece, though not so heavy as to weigh my keys down more than necessary.  So far seems durable --I've had it just about a month and no scratches on it yet, which is nice and something I was a little worried about.

The only problem I have with it is the "Captain America" printed on the face of it --wouldn't a Captain America fan KNOW what this is?  And if someone didn't, well then, you've just got a really cool patriotic keychain, right?  The printed logo bothers me, but since it's my only complaint, I can live with it.

I would definitely recommend this to other Cap fans ...who doesn't need a shield of their very own?
