Not bad for the price. Sometimes it's difficult to get the right angle, but when you manage it, it looks really cool. I bought this for my 6 year old son and he loves playing with it and finding rainbows everywhere. This is a great element to keep a child occupied for a while and educated at the same time. I would give it 5 stars but sometimes it's a little frustrating to get the right effects from it. Overall for the price it's not bad but if you want a quality prism it's not!
