This is our second season with it, and first time using it as full time lives aboards. My wife loves it. No smell, no fuss, and environmentally it makes a lot of sense. Removing all the hoses and the holding tank freed up a lot of space. Biggest downside may be the frequency with which you have to empty the pee bucket. I'm considering installing a small pump to simplify that.

All in all, glad we changed, though our Lavac with a gravity dumping holding tank was a good set up too.
