Product review (5 stars): Homebrewer budget awesomeness!
This thing is great! I live in a climate that is prone to wild swings in temperature and this unit can control both a heating and cooling device to keep my beer at the proper fermentation temperature. While this unit excels at that task and is cheap when compared to competitors it does not come without some complexity. As other reviewers have pointed out you will need to wire in the electrical hookups yourself and the wiring diagram that it ships with suggests wiring it in a less than safe manner. If you are unfamiliar with how to perform basic wiring you may need to read up first, or have somebody take care of it for you. That being said I was able to part it together with less than $10 in stuff and I couldn't be more pleased. Homebrewers, I would suggest reading the chatter on HBT for more info if need be.
