Product review (5 stars): Versitile and well worth the money
The instructions were clear and easily understandable for an electronic amateur.  The program menus were easy to navigate and change settings with the help of the manual.  It will do two independent heat and/or cool cycles.  Very versatile! Used this product to convert a large ice freezer into a meat locker for curing meat.  I did not mount it permanently, but instead mounted a two outlet box to the bottom of the controller and a 6' power cord on the top.  This makes it portable and allows me to use it for several other purposes.  I used it to control the heater on my electric smoker to smoke the thanksgiving bird.  The temperature probe is small, only requiring a small hole to be drilled at the exact height you want the temperature to be consistent at.  The LED readout of temperature and controller status are nice and bright and can be read in direct sunlight.  This one's a winner and I'm glad to have it.

It would be nice if the programming instructions were listed on the side or back of the unit.  I attached a laminated instruction card to mine with a zip-tie.
