Happy with this thermostat. I tested its calibration against an accurate digital thermometer and am pleased to say its within 1 degree of the dial indication when set to 38 degrees.

Was looking for something to help me keep my above ground pool from freezing this winter… K-kontrols freeze protection thermostat was exactly what I needed and at a fraction of the price of similar “pool” branded products. Thank you K-kontrols for peace of mind this winter.
