I typically go on long runs every weekend in far away places with wide open spaces. After these runs, well you know how it goes... a runner can get pretty sweaty and gross. Why ruin the inside of your car when you can have a nice shower out in the open in the middle of nowhere. The Rinse Kit Pro is great in the summer time when a COLD shower is ideal. Come fall or early spring some HOT water would be nice. Well your dreams of affordable luxury have come true with the RinseKit HyperHeater. Imagine a cool fall day after a run and you have the HyperHeater available. You are out in the middle of nowhere and you can strip down and have a hot soapy shower right there after a long run. You are all cleaned up and ready to go. Works like a charm. My only complaint would be the piece of hardware that you need to thread into the heater in order to connect the propane is a little tricky to connect (especially with cold fingers). A winged fitting would be better. Overall if you need hot water for the RinseKit this thing is well worth having.
