Needed a digital thermostat to replace an old mercury one. Easy, simple, good deal, and works well.

I used this to replace a programmable Honeywell thermostat using the same wire codes in about 5 minutes. The only missing feature is a backlight enabling you to change temperate settings in the dark. Reason for this purchase: Honeywell's programmable thermostat stopped working properly.

I received a different thermostat. RTH111B. It has no backlight. And the display and buttons are completely different from the one in the listing. That's basically fraud in my mind.

Product appears to be what I ordered, but the first shipment had only one in it, not two like it said. I received the final one yesterday. I still need the third one to complete the job.
