Did not do the job for me. It does keep the head above water, but that is it. It makes me feel like I am sinking giving me an uneasy, unsafe feeling. I would not like to use it in very deep water. I had hoped it would help me with water aquatics, but it is on the pile for Good Will. Not only does it not make me feel safe, it keeps on riding up, no matter how tight make it. I tried moving the blocks around because if used as pictured, it does not keep one balanced. I will stick with my noodle. Nothing wrong with the service. This device probably works well for some, but it did not work for the purpose I bought it for.
