It fits my small adult wrist very well. The latch is a little flimsy, but so far it's only come off on its own once. It's a fun alternative to my other watch, and worth it for the price.
My main complaint about this watch (a small one): the minute and hour hands are white, making them difficult to distinguish from the background. You can tell from the image, but I didn't consider this when I bought it. Oddly, the second hand is gold - I wish it were the other way around.
