Pros: Easy set up and use. Does what its supposed to do
Cons: temp control dial and knob a little on the smallish side.
Recommended? NoGood product overall. I opted for this over the digital based solely on price. It does what its supposed to do as advertised. Good, solid product. Wish I had spent the few extra dollars and purchased the digital.

Pros: works well cheap no wiring or soldering
Recommended? YesGot this from Williams Brewing. The first one kept tripping the fuse but Williams took care of it pronto (A+ customer service). The replacement is flawless and very accurate. It was confusing at first to find out when it would turn on and when off but a few days of running to the basement to check on things and I've got it dialed in nicely. Great plug-and-play option for chest freezer conversions.

Pros: Great for maintaining the temp while fermenting
Cons: Expensive, and you need a fridge to use it
Recommended? YesThis thing is a must for anyone brewing in an area where dramatic high and low temps can be reached in a few days time, like New Mexico in the spring and summer. I ruined one batch of beer when the temp jumped to 98 degrees in April and I had the ac off, then I got a second hand fridge dirt cheap and bought this controller.
Recommended? YesWorks as stated, nothing fancy but it gets the job done.
My fermentation fridge now holds a constant temp.
Recommended? Yeshaven't used it yet - keg refigerator is not working right now - hope to have fixed shortly
