So far I had 20l canister in use. But are in the boat a little unwieldy, it also wants to nix next tip, and did not fit in my locker. So just bought. Clever solution with the pouring spout. Sealing the Berschlüsse and the Ausgußschniepel. Can also handle just fine, fit perfectly with me. I am very pleased. Only ..... An elderly black 10l canister has a significantly thicker wall .... who are here ... more flexible, feel thinner. Well let's see.
