My daughter does great with this product. I had a hard time finding a product that would work for her. She only has one arm and a "nubby" as we call it. This swimmi allows her to have her nub free to use. She is 5 years old and a fish. Someone had given me one of these last year. We put a pool in this year so I ordered a bigger one for her this year. The only problem I had was I wasnt able to find a weight limit for the sizes, so I ended up ordering two. Not a problem I kept them both, because my rule is if you cant touch the bottom you have to have something on or your parent in the pool with you.
