Great!

This is a great product to build your keezer or kegorator. No problem getting set up and very accurate. My kegs, in a keezer, stay a wonderful 38 degrees.

Bought one about a year ago for my keezer and love it. Recently purchased a Kegerator and wanted more accurate control of temperature. Got it on sale and it was shipped promptly. Very happy with the product and the service.
