Rated 2.9 out of 5 by 34 reviewers.
Rated 1.0 out of 5.0 by Garbage, but what other choices are there? On my 3rd one of these now. Other reviewers are absolutely right that the temperature on the thermostat is never correct with the actual temp. Always off by 10+ degrees. Last one stopped working in the middle of the night (where my <1 year old sleeps). Took it out to see one of the terminals was completely burnt (pictured). This unit had only been in use for a little over a year (winter months only). The main issue I have is finding another option. I can't seem to find any 4-wire 240v electric thermostats. Maybe I'm not looking hard enough, but the bottom line is that these are awful products, and not reliable at all. December 10, 2014
Rated 3.0 out of 5.0 by Baseboard Thermostat Instruction are for the professionals, Thermostat setting is off by almost 10 degrees this is common on this type of product. Looks good compared to some others of equal price. September 15, 2015
Rated 1.0 out of 5.0 by JUNK-same experience as BoBC's review (from 1/28/13) I had the exact same experience as Bob C (see prior review from 1/28/13) and have gone through 2 of these over the past year. They work okay for the first few months but quickly become very unreliable and you have to turn the dial progressively higher to get the desired temperature. I also called Honeywell and they are particularly unhelpful. I disassembled the second unit to see if I could diagnose the issue. It appears the contacts that comprise the switch inside become corroded after many on/off switches (each of which appears to generate a small electric arc) and the contacts begin to act as a resistor and generate internal heat, which then turns off the thermostat before it reaches the desired temperature. Solution: I've replaced the second unit with the White Rodgers 1A66 thermostat (I only found it online-quite a number of sellers; Home Depot unfortunately doesn't seem to carry it in stores or online). It appears to be working perfectly after several months. September 22, 2013
Rated 1.0 out of 5.0 by Junk I've now gone through 3 of these thermostats in the three years I've lived in my house. They are accurate when new and first installed, but by about a year later they are as much as 10+ degrees off . . . in other words, I have to crank it up to the 80 degree setting to get it to call for heat at 68 degrees. When I've called Honeywell about it, they just tell me they've never had this kind of complaint and direct me to warranty service. January 28, 2013
Rated 3.0 out of 5.0 by Acurracy issue I just installed this Honewell Thermostat. It is easy to install as with most electric thermostats. Unfortunately mine is 5°F inaccurate. 65°F is actually 70°F when it cuts off. This was tested with 2 electronic thermometers that were half a degree off from each other. I like the design and maybe I got a defective one and will exchange it this week and we'll see. If this is the case I'll update my rating. There is nothing more frustrating than to do a job twice.

Rated 5.0 out of 5.0 by Easy Installation, Good Performance Product used to replace defective electromechanical thermostat on 1400 watt 120VAC portable baseboard heater, not its original design use (wall mount thermostat). Product was easy to install. It has good sensitivity and range for given temperature settings. Performance to date (just less than three months) has been excellent, meeting all expectations.

Rated 2.0 out of 5.0 by Not accurate Hmm, I have the same problem as the other reviewer. Room is 40deg, set thermostat to 50, gets room to about 43 and shuts off. I turn the thermostat and the click is heard at 50. Turn it up to 70, room gets to 50, I turn the thermostat and hear the click just under 70. Something is wrong with these guys... On the bright side it is a simple and clean design... December 31, 2010
Rated 1.0 out of 5.0 by Extremely disappointed Have older model of this type of thermostat (not same model #) in all rooms in my house since 1966 when house was built. They are all working fine yet, except 2. Electrician replaced one with above model one year ago, and it worked about 6 months, and then it blew, making the room an inferno (glad I was home at the time). Purchased another one and had electrician install it about a month ago also, and if you want 68 deg., you have to set it at about 72-73 deg. Why can't they be made like the old faithful ones that lasted 40+ years???? Let's see how long this one lasts! Please, Honeywell, make this product into something to be proud of and trustworthy!! Let us know when this happens. March 2, 2015
