That was fine with me
It would have been 5 stars, but after the second time I used it, the vibration setting quit working. You can only use the heat function if the vibration or bubble option is selected, other wise, the heat will not operate. That was fine with me, but the vibration setting completely failed, leaving only the bubble/aeration setting which isn't my preferred option nor is it the quietest.
Rating: 2 stars
