Rated 5 out of 5 by from An EXCELlent alternative to septic system I have a cabin in Northern Ontario on the side of a hill that prevents the installation of a septic system. I bought one of these 10 years ago and had few problems. My only caution is to do the maintenance religiously. It took 10 years for poor maintenance to catch up and I have to replace mine. The step is rather small, so building a wider and stable step is useful.

Rated 4 out of 5 by from Nice Nice composting toilet, easy to install, seems to work well. Bought an oversized one for the usage...time will tell if that was worth it.

Rated 4 out of 5 by from With knowledge works out okay The composting toilet is what it is. In order to make compost you have to have the action to make it work this has it. But for comfort one thing is missing is the proper size step up to make it comfortable to reach the height needed to be relaxed I personally built a better step up for ours now every thing out just fine. I. Think in the long run this will fit our needs.

Rated 5 out of 5 by from So far so good... This is a brilliant product which meets our needs. The ability to operate a toilet without running water is phenomenally convenient. The toilet is odorless, the hum of the fan isn't as obnoxious as we had expected it to be and the required steps for maintaining the correct balance in the drum are not complicated. The toiled does require a fairly high step up which might prove difficult to persons of limited mobility or height, but that is a small price to pay when compared to all of the pros.
