This video shows the updated Fermzilla All Rounder. It really addresses all of shortcomings I see in my All Rounder. I don't need another one, but I'll probably still get this one when it's available here!

Edit: I just found it on William's Brewing for $100.

I like everything about the upgrades, except that I tilt mine when transferring to keg. I wonder if I can still do that with the hex base

My only real problem is getting the sealed part of the lid off. I also tilt mine to get every drop out. But the hex may be nice since sometimes i need it to be stable when I’m moving it. I know they make straps for that but still. Also there is a date stamped on those, probably marketing but only guaranteed to hold pressure for a period of time.

The video shows how to use the handle to pry the lid off the fermenter. I also loosen the straps and tilt the All Rounder when transferring out of it. I'll just have to use shims like I do with my Speidel. The only remaining thing I would like to see would be a volume added during manufacturing instead of manually applying an adhesive strip and hoping you get it applied straight and vertical.

I think the date on the fermenter is more a best practice or legal requirement that applies to all pressurized vessels. Much like having to have a CO2 tank recertified every 5 years.
 
Yeah mine “expired” a few years ago.
 
Has anyone tried a coating of vaseline on the lid threads? I use that trick with mason jars, lids open right up.
 
I don't know I put a bit of keg lube and don't have to tork it to tight
 
After tightening the lid I back the ring off just a smidgen, never have an issue removing the ring that way. To remove the lid itself if it is "stuck", I back the ring off about one turn and hit it with Co2 until it pops.

good advice also On a fermenter or keg with a tri valve set up don't take the clamp completely off when under pressure
easy way to loose an eye

Or potentially much, much worse...
 
They need to address legal liability. Testing it is easy: fill it with water, then pressurize to some value (like 30 psi, twice what you might ferment at).

Why filled with water? Craig, you’re a hydraulics guy, you can explain.
 
Just a little out of date, but essentially I pressure test it everytime I brew, right!

strange
mine is out of date from 2023 also
I can't remember when I purchased it but not much before that
covering their butt for sure
I never go above 15 psi

essentially liquid is virtually non compressible, the less gas in the vessel when pressure testing the less danger should there be a failure.
I'm not sure what the compression ratio would be for Co2 at 30PSI, but this is essentially how bombs work, stored energy.
For instance 30PSI of air in a vessel contains far more potential energy than water at the same pressure.
Tried not to get too technical @Donoroto

Bingo. When the vessel bursts, the compressed water doesn't expand, so you get wet. With a gas, it keeps expanding, as in boom.
