Review on Chemical dry closet Thetford Portable dry closet THETFORD Porta Potti 165 (92806), 21 l by Mateusz Grzesiak  (M ᠌

When using all existing cashbacks, an acceptable price is obtained. It is better to take this company for a thousand more than to suffer with Chinese from hypermarkets. Has pros: It is comfortable to sit, the drain design eliminates leakage even if the o-ring deteriorates. Looks pretty. You can find spare parts in case of breakdown. Large tank, no need to constantly run to endure. Different cons: When you open the valve to start using it, it comes back a little, you have to either hold it with your hand all the time, or put something under it. In my case, a ball of thread came up. There are no handles on the side to carry the entire toilet.
