ELECTECK Digital Thermostat with Large LCD Display, Non-Programmable, Compatible with Single Stage Electrical and Gas/Oil

Nice backlit screen that is very clear and buttons are very responsive. Easy install and quality seems solid

Ease to install and works. No complaints from my grand parents that have "new technology phobia".

Was easy enough to install by being careful with being sure wires went to correct location. Worked well for heating, but I had a problem with the cooling operation and had to call a HVAC technician. The previous thermostat was not installed correctly with a problem of wires in the furnace mismatched. Older programable thermostat was not reliable, maybe because of the wiring problem. The technician initially advised against using an unknown brand but he replaced it again after correcting wiring problem caused by the previous installation. saying it looked like a OK unit. The installation manual seems to be well written, but the operation manual is not very good and takes a bit of thinking to understand. Best feature over other brands is the large display of both room temperature and set temperature.

Worked perfect, nice but display

It function outstanding. But the batteries do not last long.
