I bought this for my dog as a christmas gift, unfortunately she found it a little early. She absolutely loves it! I got the red (which actually glows more pink) and it is so easy to spot flying around the dog park. I bought it because I was tired of loosing tennis balls at the park when it starts to get dark. It also fits in the chuck-it, which makes it even more fun. Although I would not leave her alone with it (due to rubbery material that might get chewed up), I think it is great under supervised play. I have not tired it in water yet, although it says it is waterproof and looks very well constructed.
Bottom Line Yes, I would recommend this to a friend
