this product is used as a teaching aid, and as a training method in the pool. It works really well, and is a lot of fun to use. I would strongly recommend this product for those who have a problem keeping themselves boyant in the water.

Not as much bouyancy as I expected from a large kickboard

This is the largest kickboard that I could find at a reasonable price.  It still doesn't hold up an adult without effort, but it does work.
