Not great for me
Rather clunky for a normal sized tub. If you fill the tub enough to cover you completely, water spills out everywhere because of the bubbles. It cools the water rapidly so you get cold quickly. The air hose pulls off from the mat while in use because the mats suction cups are not strong enough to hold it down. So I find myself constantly adjusting it and trying not to make a mess and keep warm as the same time. I have a bad back; i bought this to relax. Its more trouble than it's worth if you're looking to ease a sore body.  Maybe it would be better in a really deep tub, but it's not great for my normal sized tub.
