High quality heat jacket
This worked great, it was always convertible to the touch even during the boil. I have not brewed without it so I don't know if it saved energy holding the mash at temp.

Don't Leave Your Brewzilla Out In The Cold!
I have the 120Volt, 9gal., USA version of the Brewzilla. I have used the kettle with and without the jacket and I must say that it is a worthy purchase. The Brewzilla will work as advertised without the jacket, but the unit will come up to temp noticably quicker and hold temperature more steadily with the jacket in place.

I brew indoors, in cold country but in a heated environment and I still use it for every brew and I believe it improves my brewing experience. If you brew outdoors or in a cold environment, then I think you would especially benefit from having this jacket adorn your kettle too. The fit seems tight, but it is neoprene and it will stretch around the kettle with some effort.

The jacket has stayed tight and great looking for 28 brews as of 10/2021 at about 5 months of age. I regularly clean it by wiping it down with a clean cloth after brewing and it still looks like brand new and does its job effectively. I have not removed it since I put it on. I think it is tight enough that no schmegma is going to slip behind it and contaminate its inner sanctum, should an accidental wort splash occur. If you have the Brewzilla, GET IT!

Great for the brewzilla
Helps immensely to keep and get to the mash temp and boil. I have both the 35L and the 65L variants.

Fits like a glove.
I bought this for my 9gal klarstien hoping it would fit and it did. Took some stretching to get on there but it has stayed.

Needed for 110v system
I bought this for my 220v system. It does a good job keeping the heat in on my system, but feel it might be needed for the 110v system. I cant see for the life of me, why, did they put the seam behind the recirc pipe? It's a PITA getting it fastened directly behind the pipe! Other than that, it's a good quality product and fits pretty good - although a little pricey!

Fits well
Fits well. Don't have a comparison of with vs without the sleeve but, it at least is designed well for the unit unlike the sleeve for my KOMOS tower.

Works but difficult fit
Works but not as easy to put on as it should be. They decided to put the velcro connection right near the recirculation pipe. Could have put it anywhere around the back or other side and it would work the same, but no. Also very tight so you gotta stretch it to put it on. And I imagine stretching a material like neoprene reduces the insultation capability vs when it's in a relaxed state.
