I bought this rather than the $89, $119 or any other products on the market only because of the water heating feature. Continually switching from 35, 38 to 42 degree is my favorite experience. If you like, there is 45 and 48 heat setting. If a foot spa can’t maintain the temperature but cooling down soon in winter, what’s the point? It is certainly worth the cost! I am not interested in other features bubbles, massage and all the other bells and whistles. They are all working just I barely use them.
