didn't actually shower with it yet but filled it with water and let it sit out all day. The water was hot after 6 hrs (didn't check before then) and maybe too hot for a shower but happy to see it worked. Says you have to rinse it with baking soda water before first use, not sure why when if you throw in your camp gear you're probably not going to have warm water and baking soda on hand at camp. Note we were heating on a 90 degree clear day.
