The product is well built. It is advisable to start with warm water. The heater is powerful enough to keep the water warm but not strong enough to heat the water from cold. My kid and I enjoy this very much. The bubble is very soothing. The massager (vibration) is a bit too noisy so I am not using it. Overall this is a good product so worth recommending this.

This footspa really does heat the water. Other models and brands claim to heat the water but never actually achieve this claim, however, this model keeps water warm and can heat warm water up to around 40C. This is awesome for the colder weather.

There are press button controls that individually control the heat, bubbles and vibration, any combination of these modes can be on or off individually. There is also a timer for 30, 45, 60 min.

I put epsom salts into the footspa and this works well to relax my body muscles, as good as a bath.

Definitely try this footspa if you have been disappointed with other brands, your disappointment will end!

September 7th 2018 Update: Best foot spa ever

I could have sat there for hours if I could. Many other reviews of other products say they don't heat the water; this one does. Having just the heat and vibration on does let the water get a bit too warm sometim...
