I was skeptical, as I've ordered items from other places that came with "hand warmers" to keep contents from freezing. Those only have a few hours of life... This Heat Pack was still generating heat when my package arrived! Nice!
The cactus came with the pot broken which is ok cause I repotted it. The box was badly beaten up in shipment and I don't think the heat pack was at all necessary. Infact the package was ice cold and the heat pack was rock solid.
All the plants were perfect and the heat pack was still warm.
Everything was perfect! We had 2 plants that fell apart but that was fine because we ordered extra and the heat pack kept the plants warm!
Heat pack was still warm when succulents arrived in upstate New York to 30° weather. Plants were perfect
