Works as expected
I bought this after my spa shorted out again in a storm.  I have a chronic pain condition and needed something to replace it.  I saw this on Amazon and read the comments both good and bad.  After careful consideration, I bought this product.  It works just as advertised.  The mat adheres to my bathtub really well.  The bubbles come out just as advertised and it helps me get that wonderful massage feeling all over.  I use it all the time and love that I can put in fragrance or bubble bath if I want.  Those who did not like it probably did not know what they were getting and their expectations were a little high.  If you want a product that will gently swirl water around your sore body, this is the product for you.  if you are looking for something that will shoot a jet of water on your sore body, don't buy this.  I knew what I was getting and love it.
