Product review (5 stars): Controlling a freezer
The wire is long enough to place anywhere. The controller also has a chain that allows one to hang it. Mine is hanging on a rear hinge. The freezer plugs in to the end of the cord that goes in to the wall. I thought it would plug in to the controller, but that is not the case.

I was concerned that it would cycle the freezer frequently, but it appears that the control range is wide enough, and my freezer is insulated enough, to not require it to cycle often.

The controls are simple and this keeps my kegs the desired temperature.
