Review (5/5): with only needing a very short cool off time before using them on a client
I've used these once so far, but I'm impressed! The rocks heat up to just the right temperature, with only needing a very short cool off time before using them on a client. The stones are just the right size for my hands, and very well polished. The size of the clam shell is just right, not too big or too small. Perfect to place on a side table in my massage room. Overall, I'm very pleased with this purchase!
