I know I have said this several times down the years, but this really is the worst piece of crip I have ever had the misjudgement to lumber myself with. 7 years after it was inflicted on us, we still have absolutely no control over our thermostat, even standing right next to it. The exorbitant cost of constantly replacing the batteries, and the hours and hours and hours and hours and hours I have spent coaxing it into a tiny modicum of cooperation. Batteries were changed two days ago. ******** thing has failed again. Now can't rthe heating off.
