I have a beer fermenting in the fermzilla at the moment, warm water didn't shift the dent neither has the 15psi which the gauge is reading. Thanks for the offer of an exchange but I would much sooner stick with the one I have,I don't want to end up with one like SpaceClef has. And reading the last sentence of post 1393, I guess this is as good as it gets.

Fermentasaurus Gen 2 - 27L
We have decided to make some further changes to this and we have re-designed the collection container. Previously you would probably notice the Fermentasaurus 1 has a collection container that had no easy way to release pressure. We did get some customers get hops block in the container then this could cause a bit of a hop explosion effect when the collection container was removed. So we have re-designed the collection container so it has 3 openings on the collection container. You can easily attach ball lock posts to these openings as well so this means you can more easily purge oxygen from the hops or whatever it is that you are dosing the container with. The other thing is that you can also dispense samples from this collection container or use it to oxygenate your wort. So this will give the collection container several additional functions. So sorry it's taken longer than we anticipated but we simply don't want to start selling the product until we are really happy with the end product.
