Rating : - not bad, but not great
My 11 year-old daughter had to have this for Christmas. The device itself is easy enough for her to operate on her own, but the gems themselves are easily damaged, lost, etc. so the handful that come with the original device are not enough. My daughter loves them though and - unlike so many other things I've bought for her - it works as advertised for the most part, so I consider it a good buy. I wouldn't pay any more - but its worth the price.
