Very basic but does the jobReview by Mike
How do you rate this product?
The mat works as described, it raised the temperature by some 10F, which was quite crucial, since my brew was at 66F before (quite cold in NY right now). I just wish it had a very basic controller allowing for, say, two temperature settings for the times when it's not that cold in the apartment, but still less than ideal for Kombucha.

Hot item!Review by Steven
How do you rate this product?
I purchased the large heat mat with a 1 ft extension for my 3 gallon crock and it is perfect. The heat mat keeps the crock about 10-12 degrees warmer than my house. I also noticed that it helps prevent large temp swings when I turn my heat off at night or when I'm at work. This keeps my SCOBY happy. (Posted on 2/15/2016)
