Performs as advertised, but it is time consuming to remove and add sections.

Overall, very good product.  A little hard to remove each layer of foam as child get better at swimming.

This is the best flotation device we have found. We have 4 1/2 year old twins and they are serious 'WATER DOGS". This allows us to have peace of mind when we are at the pool or the beach. I recommend this product to each and every parent!

We recently ordered these since they were similar to what our girls were using at their YMCA swim classes.  We previously had been using arm floaties which were hard to put on and uncomfortable for the kids to wear.  These back floats are not only easy to put on, but they have helped tremendously while the girls are learning to swim.  
Within a week, my 6 yr old has already taken one of the layers off.

allows swimmer good range of movement

This is a great product for those "early" swimmers.  My twin girls don't mind wearing it and I feel more comfortable taking them to the community pool.  It is easy to put on and take off and not too uncomfortable on hot days.
