It's an adorable mirror, a good size, though far too thick, and designed like a MacBook Air (except not as thin).
I don't like that it's white (I would've preferred silver like in the pictures), and it looks and feels very cheap. The hinge isn't very strong either; it doesn't hold its position past a certain point, and it's the type of cheap thing whose function deteriorates with time. It's not particularly impressive.
All in all, it's a cute gift, but don't expect anything amazing.
Update: I've had this mirror for a few days and it no longer closes. It's pretty much just been in my purse, haven't used it but once or twice, and whatever held it shut has stopped working. It's a cheap, useless gag gift.
