Hey Welly2, and others on this thread. Just thought I'd jump on and give you a rundown on our fermenters, I actually started a thread here some time back but post release mayhem/new baby/managing the other half of our business meant I didnt actually get back here to update. Thread here

We're stoked to finally have product in Aus, these are a fantastic fermenter which as you suggested sit squarely between the SS brewtech product and regular brewing buckets. The product is made here in NZ, and all of the bolt-on bits are either 304 stainless or Silicone. They handle a few PSI for transfers and have nice big 1" dump valves for harvesting yeast, come in 30L and 60L sizes (can actually take those batch sizes, with head space). The insides are super-smooth, and the logical comparison is always with the more expensive product, given the quality of the product we are producing. Apprehension around plastic is largely unfounded/has been quashed over time, as most brewers always start in plastic, and often never migrate up to stainless anyway. These are a super-tough moulding with a nice smooth interior, and if cleaned and sanitised correctly will indeed last a lifetime, wont dent, and contrary to popular belief, unless you are using a sharp metal object and being a tool, will not scratch on the inside. I scrub mine with a fairly firm-bristled brush and it still looks like the day it came out of the mould. Aside from that, they are what they are, a good honest product, designed for serious home-brewers. Ive easily cracked 50 brews in my ones, and barring some catastrophic fail, will see many hundreds more Im sure. This isnt a cheap product, we have not skimped on materials or hardware. "buy cheap, buy twice" doesnt fit our mantra..
We have some pretty nice updates coming soon too so will keep you posted on this forum and our facebook. Welcome any questions etc you all have. Cheers for the interest
