Does what it is intended to do and is comfortable.
Most buoys do the same job. Go for the least expensive one. I'm 122 lbs and slim and got the junior one, but not buoyant enough. Ironically adult one is a touch too buoyant. Oh well, it'll have to do. Greg
Used for isolating legs to get that maximum arm workout in the water. Goes right into my roomy, new Club Swim mesh bag bought on this site.
I used it to train for several Triathlons and continue to use it. I bought it primarily for price. I can share that the performance has been excellent, no issues to report.
My kids use it for swim team and it is of equal quality to higher priced brands
This is a MUCH CHEAPER item than sold in stores!!
