i been used aquajogger equipment and accessories 5 days a week    cent 2003 and it all great to work out with.

I love these modules because the rigid belts are uncomfortable for me.  You can put these on a belt and wear them so the module is located at your back.  This provides the stabilization for water aerobics without the discomfort of a rigid belt pushing on my diaphragm.  However, from the illustration,  it looks like there is an accompanying belt for these modules.  That is not the case.  It's a small strip, about a foot long, of velcro material.  You need to order the belt separately.

These are very rigid plastic and they rub and hurt around the middle of the foot.  I can only wear them for a brief time.  I got them for going from the locker room to the pool, so that problem is not too severe for me to use them but it would have been nice if I could have used them for sandals too.  I wouldn't get them again.
