I've just ordered a Fermzilla All Rounder. Most of the reviews of them seem really positive. I went for the 'All Rounder' due to it being a bit less complicated than the conical with the collection jar so less to go wrong!
Up until now i've fermented in "Better Bottles" as I like to be able to see what's going on. That said, my Better Bottles need replaced so I went for a standard bucket (Better Jugs) for an interim solution and I just cant seem to get a seal so my bubbler does nothing! It ferments fine but i keep having to open the bucket to take a reading and see what's going on. So it's back to a clear fermenter for me with the Fermzilla.
The PET of the Fermzilla is (meant to be) non porous compared to the Better Bottle so I shouldn't have to replace it as often.
