If you have the money to splurge, it's a good set. But you don't get a ton for the money.
The face stone has been gentle on my acne prone skin. I use it on days where I'm feeling tight or dry, but if used in the T-zone, it does lead to some break outs. The face stone is cost effective, it will be a long while before I run out.
The body stone is slightly difficult to use. I dropped it once and I never got all the dog hair off of it (husky household) and when maneuvering around post shower, it's pretty easy to drop. (Trying to rinse it just lost most of the product).
It's found its place on my night stand and I enjoy using in prior to bed to add a bit more moisture. I really do recommend it for that purpose, since it doesn't leave you as sticky under the covers as most lotions.
