Review on Portable Electric Spa Massage Stone Heater Set - Heated Rocks and Warmer for Rock Massaging - 12 Large/Small Black Stone Kit with Bamboo Heating Case - SereneLife PSLMSGST65.5 by Trent Kraft

This product works exactly as described. The box heats up to the desired temperature (in 5 degree increments) in about 20 minutes, depending on how hot you like it, I use it at 135 degrees Fahrenheit. The 9 stones included (6 large and 5 small) are really smooth and retain heat very well. I'm sure you can add your own heat resistant bricks to add to the 9 included bricks. Also try to warm the area where you are placing the stones as different parts of the body tolerate different temperatures. In my own way. Application: The center of the metal heating plate in the bamboo box seems to be the hottest spot. So I would recommend putting the big rocks in the middle and small rocks around them to really heat up the big rocks well. If you're lying on your stomach and want to achieve even heat transfer in hard-to-reach areas of your back, it's definitely best to have someone help you. If you want to use it for muscle pain or relaxation on other parts of the body, you can easily do it yourself. and pay for expensive therapy sessions. It's a good way to relax and relieve stress after sitting in an office chair for a long time or standing at work all day. runs very easily).
