The product works OK. But the lack of written instructions is frustrating.
I don't want to go on line to learn how to use this product!
No, I would not recommend this to a friend.

Replaced my non-wifi thermostat with the T9 and I couldn't be happier. It works as advertised and is easy to set up and use. Highly recommend!

Beware of buying from Mass Saves

Verified Purchase:Yes
I got my thermostat from Mass Saves and it has been horrible. My breakers keep tripping. I had to pay for an electrician to come twice so far. My last WiFi thermostat worked perfectly. I am going to put the old one back. I was trying to upgrade. I think I got lemons.

Hi efficiency Wi-Fi thermostat programmable

This product is great, especially if you’re thermostat is upstairs and you hate climbing steps you can actually operate this one from your phone, which makes it very convenient so you don’t have to clean stairs every time to change the temperature
I would recommend this to a friend!

Dumb thermostat

I thought knowing the weather made it smart and energy efficient. That is wrong. I've caught it turning on the a/c right before a freezing rain night cause the inside temp went 1⁰ too high for its liking. When obviously the house would drop in tem0 over night. Also even though I have sensors and it's supposed to average the temp. Multiple rooms have been well below the set temp for the heat to cut on

Very happy that national grid changes our old thermostat and now I can control the temperature from my phone even though I am not home. Also I can see the outside temperature
