Arctic Alaska installation and review
A great toilet that's a real game-changer when it's 30 degrees below zero outside,and saves me a grueling walk to the outhouse..Only problem after 6 months of use is the toilet stand..I recommend replacing it with a $2.80 cinder block from Home Depot

So far no problems. I vented it and there is no odor. Easy to maintain. However, I haven't owned it long enough to see how well it composts. Will try to update my review later.

Easy install and kids actually use it
The unit was very easy to install and was up and usable in about 1 hour. A quick call to sun-mar and all my questions were quickly and fully answered. Home depot you again have delivered a great product.
