I've done a couple of brews in mine so far with no issues. Nice solid piece of kit. I got a really good deal with mine. Got the discount so 100 quid down to 69. It duly arrived via ups and I noticed that although double boxed something sharp had pierced the box and put a tiny dint in the rim of the lid. But miffed but sort of damage I would do myself dropping in sink etc. Not enough to complain about. Hey ho on we go. Got a satisfaction questionnaire from klarstein, filled it in explaining above. They replied I could either return it f.o.c. Or get a 30% discount. I opted for the discount and they refunded me £42! So, the fermenter cost me 27 quid! Not sure where they got the 42 quid from, but deffo a result!
