BrewJacket Immersion Pro

Recently purchased a Brewjacket, it's arrival spurred me on to do my first all-grain batch of a Czech pilsner recipe. I lack much brew storage space in my house, much less one for a lager fridge, and what space there is available is warm. The Brewjacket is perfect for my needs. Equipment set up is very easy. Important: read the PDF online manual - temperature calibration is important. Follow instructions to sanitize the probe, the metal bar, and the PET container (in my case, a 6-gallon carboy). The supplied temperature probe was spot on with a freeze/boil water test; the manual does guide one on calibrating the controller head, if necessary. After attaching the unit to my batch in the carboy, I was able to snuggle the carboy with 5 gallons of wort into the jacket without too much difficulty. (Tip: use a carboy strap hauler to insert the carboy into the jacket with a straight, downward motion into the jacket cavity). The controller, when it's running, is a bit loud, so keep it at some distance, close the door, or shove it in the basement. My impression is this item, though expensive, is perfect for my needs. I won't be making a lot of lagers, mostly ales, so this single unit is all I (think I will) need. Glad I bought one! Apparently, the company now makes jackets to fit FastFerment and SS Brew Ferment Chronical 7.
