As a replica, this is a very attractive item.  It looks like Hermoine's time turner; it spins; and there is the inscription on the sides.

Drawbacks:
1) It's very fragile.  Holding it in your hand, you can tell that it's not something that'll withstand rough play. The glass/plastic in the center is very thin.  It's something you'll keep in its box, not actually use.

2) The chain: It's ridiculously short.  It's made of a cheap-quality metal.  It doesn't have a normal clasp but instead has the rough hole + pin link.  Worst of all, the chain isn't connected through the timeturner through a normal round clasp; it's permanently attached on both sides of the timeturner so you can't even buy a better quality replacement chain for it.

Overall Opinion: Despite the nice look of it, the timeturner is absurdly priced.  The quality of the product I received did not match the pricetag.
