Must have, but could use some improvements
This is a must have for better temperature control in your brewzilla. I'm a bit befuddled that the velcro line is next to the return pipe, making it really difficult to put on. Its also a bit frustrating that the cutouts don't line up very well with the handles and the spigot.

overall a must have, but could use some improvements.

Fits OK, Decent Quality. Best price on the internet BY FAR
The fit is pretty good, and the velcro holds it together. HOWEVER, I'm using it on my 35L Digiboil, and the cutouts for the valve and handles don't quite line up. Not a big deal, and probably won't effect the function, but it looks a little less like a custom fit...

Helped achieve and maintain a good rolling boil in my DigiBoil. Remember to hand-wash and drip dry when needed.
Added to the quality of the boil significantly.

Pretty Much Required
Don’t think about it, just but it when you buy your RoboBrew. Helps getting a stronger boil and getting to temperature faster. Pretty inexpensive too.

Update: after 5 months of ownership and 6 batches of beer, I am happy to upgrade my rating from 2 to 4 stars. The jacket has stretched enough over time and heat cycles to eliminate my complaint about it being too tight. The fit is now snug but not excessive, and it performs very well as an insulator to stabilize mash temperatures and improve the character of the boil.
As noted by another reviewer, the handle and faucet cutouts do not fit properly on the Brewzilla (aka Robobrew) V3.1, but you can make it work if you are willing to locate them way off-center. The bigger problem is that the fit is VERY tight and the velcro closure is located directly under the vertical recirculation tube. It is extremely difficult to get the thing on without damaging the tube. Why is the velcro closure under the tube? There is plenty of room to locate it an unobstructed position. The insulation works well, but the design needs some modification.

Could have been a 5 Star product but wasn't thought through all the way
Terrible fit on the cutouts... One Cannot properly Center it on the Robobrew / FermZilla without losing one of the cutouts and the jacket rolling up ... But if you off center it you can make it work.. it does what it says in helping it to heat up faster and work more efficiently then it would if it didn't have one.. for that I give it just three stars when it could have been a five-star product

Robobrew jacket
At first I didn't think it would fit but heated water in Robobrew and it , with some force fit. Boils are more vigorous now. Great product!
