It is expensive but innovative. It separates the waste, and there is no odor at all. I wish the opening for Number 2 was larger to avoid accidents, but otherwise it seems well made. It has an app that functions to switch bag types and update the unit. Its size is perfect for our RV shower and can be removed. After looking at all the options out there, I am glad we settled on this one, as the other dry flush toilets do not separate urine (Laveo, Modiwell, Clesana) and/or have to throw out the entire bag if only partially used at the end of a trip (Laveo). The company seems interested in updating and making improvements on it for the future as well. It is an investment for sure, but coming from the black tank work, this is a much easier and cleaner option for boondocking and dry camping.
