Review (1/5): Not impressed at all
I absolutely did not like this product. Prior to this purchase I had to use the portable hot stone clamshell set and loved it. I tried this set and I did not like it. This box is heated by wires underneath a cloth sheet that you lay the rocks on. This results in spotty heat, making my stones different temperature some cooler than others. It does not heat up much. It is also extremely hard to clean because of any oil gets on the cloth that covers the heating element your basically out of luck
