The Crazy Girl Warming Massager is a heart shaped gel pack very similar to the instant heating packs often found in drug stores and first aid kits. It can be used to apply heat to sore muscles, or for a more sensual massage. It's large enough to fill the hand, measuring five inches across, and it glides across the skin, especially with a little massage oil.

For the first use, it can be heated instantly using the metal disk that floats within the gel. Simply bend it as the included instructions suggest, and the gel will warm. Future uses will require boiling to reheat it, in which case it's important to plan ahead so that the gel will have time to cool a bit before use. Always test the temperature before applying it to a partner's skin.

It's very important to note that the Crazy Girl Warming Massager is not microwave safe.

This massager does carry the scent of a new shower curtain or other soft plastic, and the ingredients are not given on the package. If you're sensitive to chemical smells, you might be better off with a stone massager, but since this product is not meant for internal use, it shouldn't pose a health concern. That said, the packaging does include a number of health warnings. Users who have sensitive skin, poor circulation, heart disease, or rheumatoid arthritis, or those who are pregnant, are instructed to consult a doctor prior to use. While that's a pretty standard disclaimer, it's worth noting.

Also, it's never a good idea to apply heat to fresh bruises, swelling, broken skin, or recent joint injuries. Those situations call for ice. Fortunately, in a pinch, the Crazy Girl Warming Massager will work as an ice pack if placed in the freezer, although that's not its intended purpose.

I tested the Crazy Girl Warming Massager on my own sore muscles, and found it quite soothing. I also popped it in the freezer to try it as an icepack, and it worked quite well. It holds temperature for at least an hour, which is much longer than necessary for either of those uses.
