doesn't get very warm
Smells strongly right out of the package. Takes a good long while to heat up fully. Like, probably 20 minutes. I’m not convinced the temperature gauge is accurate, it didn’t seem as warm as it said it was. It was more cozy than “this is helping my muscles” level warm. Also it's fabric, but it's not very heavy and it's not very drape-y. So if you’re looking for very low-level heat, maybe just to warm up your lap or back, the rocks do seem to the diffuse it efficiently, but it never does get very hot. It does fit in the included storage bag.
