followed the directions it works great
First of all you have to get the bottom of the bathtub wet,lay the mat in and the suction cups stick very well. They stick so well when I try to lift it I have to break the suction under each cup.I put the hose at the end of the tub next to my head, not coming in at my feet near the faucet. I turn the air on and start the bath water. Yes the air heats up with time it isnt instant hot air blowing out it takes a few minutes/3 maybe. It heats up by the time the water fills the tub. Also, it doesnt fill up with water because I keep the air on while it is under water and as I hang it over the shower rod after I am done. It only takes a minute or so and it is completely dry.I suppose if you leave it in your tub.... I would leave it on until the water is completely out of the tub. This product blows air into your bath water,it is soothing and refreshing. It is not a jacuzzi which is what some of the other buyers seem to expect. I also place it off to the side a little for maximum air flow.I think it is well worth the money.
