Just figured I'd give a little update now since I've brewed a good amount of beers using my Brewmaster Bucket's. So far I'm loving them and think they've been a significant upgrade for my brewing. The ease of removing the lid compared to my screw off Coopers plastic fermenters is such a huge difference. Cleaning is also a huge improvement in ease and speed. Having the digital thermometer has been awesome and I've tested it to be extremely accurate. Taking a hydrometer sample is also so much easier as my plastic Cooper's spigot's had a lot of resistance and would often turn the whole spigot if not held with another hand - which is a bit of a pain to do when also holding the hydrometer tube. I've not had a single instance of leakage but I will say I did upgrade all my o-rings to slightly thicker one's from the o-ringstore.com. Not because I had any issues, just because finger tightening easily warped the original o-rings where they'd pop out on a side if slightly over-tightened.
Last week I did my Hefeweizen and thought there might be some blowoff as even in my larger Cooper's fermenters I've had aggressive Hefeweizen fermentations that bubbled up out of the airlock. I used their 90 degree blowoff elbow attachment for the lid. I didn't get any blowoff but it still worked like a charm. Originally planned to buy the domed conical lid for the extra headspace when doing hefe's but now I don't think there's a need and the blowoff attachment will do find if needed.
Anyhow, still loving my Ss Brewmaster Buckets... loving them big time!
