Bought one about 5 years ago to replace the old fashioned RV thermostat. Replaced the batteries every year with lithium type.First thing I noticed was the batteries fit too tight in the compartment such that it did not make contact until I shifted them.After 5 years, the thermostat went unreliable. It stopped turning on the furnace by itself. Batteries good, contacts cleaned, furnace sensors and control board checked, but it kept failing at the worse times...middle of the night in winter.Unsure about reliability for such a simple circuit, especially based on other reviews.Hoping I am wrong when I replace it. Prefer not to go back to a spring thermostat.
