I bought this for my son to use at the pool. He is still learning to swim and this helps occupy his time in the pool. I read the Amazon reviews which gave it a 4 out of 5 stars. We wait each year to use the local pool with our August only pass. Today is August 1st and we were excited to go. Both my son and daughter played with these for about 20 minutes today. I would throw them and they would retrieve them. On occasion they would throw them to me to catch. One of them I caught and on hitting my hand it broke. About 5 minutes later they threw another one that landed on the pool deck and broke. Please see image of where they broke. The product does work well since after it sinks it stands on end so it easier for a child to reach down and grab. I liked that part of the product. Even though the product broke they are still usable since the white (heavy part) is still attached. However if it breaks on the other side of the white then it will be useless since they will not likely sink. The other thing I like about the product is you can write with permanent marker on the white section. We wrote in our last name. I purchased this product July 22, 2014 for $6.25.
