I ordered these as the instructor for a new class.  They work great, but are not as long in length as the one I previously bought in a Speedo kit.  Some of my students cannot wear them.   The do not fit larger people.

The flotation belt didn't work well for me.  With back problems I needed the support of other type of belt.  Should have paid for the higher priced product as this just isn't for lme.

I am a small person and this product , I thought, would be more comfortable but "pinches" my waist. Too bad cuz they are so lightweight.

I used it in my water fitness classes, while I recovered from a broken foot so not to put press on the foot.  It worked great.  I can add or subtract the amount buoyancy that I needed.

I purchased this belt because of the adjustable bouyancy, which I do like. It would be more comfortable on me (I'm 5'1") if the length of each block was shorter (it pushes against my ribs). Otherwise, it's comfortable, light weight, and folds easily to keep in a small locker.

We use the belts for a deep water aerobics class.  They work well except if  you don't get the belt pretty tight it moves up your body.
