21 Pcs Hot Stones Massage Set, Hot Rocks Basalt Massage Stones for Home Spa Warming Therapy Relaxing

I bought these hot stones to use in my spa. Used them plenty of times! Love the variety of stones! They do take about 35 minutes to heat up really well, but it doesn't bother me, I turn them on and prepare for my appointment ahead of time anyway.. If you're someone who is always late or doesn't have patience than find hot stones that will heat up faster.. I lay them on a seperate towel when Im done using them to avoid getting the warmer dirty. I wash them with soap and water and than lay on a towel and spray with cavi spray and let them dry before putting back in the warmer..

Does not have an off/on switch but I love the variety of stones

My desire was universal volts but its only 110 volts , but I like it.

They heat up and gets really hot but they also gets cold to fast. Too hot for the skin and if you wait for them to cool off fir about a minute they will become cold fast once they are placed on the skin. Buy and use with your own judgment because everyone's skin is different. Some people can probably stand taking the hot temp and doesn'thave to wait for the stones to cool off. If you can take the hot heat without having to let them cool off then this will work out just fine for you & it will be well worth the money for it and you would also get the pleasure from the timing of the heat rocks. Others that can't take the heat such as my husband might need a heating pad instead lol

Careful when using they get hot and it only has on or off so be careful other then that I love them they work very well
