We did some real tests with the Dry Flush this past summer and brought a unit to Burning Man, a week-long survival festival deep in the Nevada Desert. There were several of us at the camp and we all used the dry Flush toilet when needed. We kept the unit in our trailer and were pleasantly surprised there was no odor at all from the toilet. The battery worked great all week with all of the uses. It’s surprisingly simple to use and clean-up/disposal of waste was super easy! Very Smart design! Comfortable and sturdy, the Dry Flush will be the perfect accessory in our new HC1 Ultralight Travel Trailers! We call it the “SPACE TOILET” !!
