If any of you figured out what the heck that thing is just by looking at the picture, congratulations. We had to read the copy to discover it's a portable sauna because, quite frankly, we didn't know there was such a thing.

The Solo Portable Sauna uses something called a Solocarbon heater, which in turn produces something called far infrared heat.

It can be used for relaxation, therapeutic purposes, or to drive a wedge into your marriage--simply fail to tell your spouse you're buying one, then let him/her come home and find you lying down inside of it. Use it regularly, offer no explanation, and refuse to discuss it.
