Title: Calibration way off...
Product review: I bought this despite 1 star average because I had a prior dirt devil that looked just like this morphologically and it lasted for 2 years.Product immediately developed condensation inside housing.Calibration is off by 6-8C. It is showing 89C pool water as we speak. This is Minnesota and I heat the pool to 80-82.Update: Completely died by late July.
