We have the Zodi at my camp and it workes ok. Before we got one a week at camp was rough on the body due to sweat and chaffing. We are trackers and move all day and usually cover several miles. The water isn't real hot but warm enough to clean up with and allows soap to be used. The temp is usually in the 20's and 30's with snow and we shower outdoorsstanding on a pallet in the shelter of spruce trees. That warm water is heaven.
