I love the bubble action
This is my first foot spa. I soak while watching TV so it is not noisy.  I fill it with warm tap water and it keeps the water warm.  I love the bubble action. The heat only stays on if you choose either the bubble or the vibration. The hidden spout to pour out the water is wonderful. My only complaint was the comfort of the bottom which I fixed by cutting a plastic sink liner in two for a nice smooth place for my feet. I also bought a dish drying mat so I can put it between my ankles and the plastic edge of the spa. The dish mat is easy to wring out when done.  Now I have a very comfortable foot spa!
