Title: This is an on-off switch, not a thermostat
Review: I was really hoping this would work as promised, as there are almost no options for line voltage cooling thermostats. Unfortunately what many of the other reviews say is true. This thermostat has such poor sensitivity that it basically functions as an on-off switch that looks like a thermostat. I have not had it 'trip' due to temperature changes, either in the on or off direction, more than a couple of times in months of attempted operation. I even sent the first one back and got a replacement because I thought it was defective. Wish there was another alternative that looked decent; unfortunately most look like they are from 1970.
Is the review positive or negative?
