Took a week of research to finally make this purchase. After reading many conflicting reviews on amazon and other sources I decided to go with this one. I found mostly good reviews and several bad, some possible fake reviews. I received my foot spa yesterday. The unit is large/deep has a sturdy 3 prong power cord, however a little on the short side, I used an 3 prong extension. The heat works great and fast - I put in slightly warm water and it got hot fast, had to turn down temp. The bubble message effect is minimal. Rollers decent. Convenient casing to put epsom salt or other product. overall happy with purchase. If you're looking for heat and size this is for you. If a lot of bubbles or message are important may want to try another, however many others don't heat water.
