Pros

About a month between emptying the solids bin for two people, by the maker’s figure
The fan sips so little power that a small battery runs it for weeks
A crank mixes the solids, so they dry faster and smell less
Five year warranty, longer than most rivals

Cons

The urine bottle needs emptying every few days with two people
At 19 in deep with a side crank it needs more floor space than the slimmest van toilets
No NSF/ANSI 41 certification is stated, which some health departments ask for
