Waste of money
Do not purchase this item, it is garbage. It lasted a few months then it just started falling apart. The metal pieces on the inside all fell out. A complete waste of money.

    I haven’t had it long, but it seems to work great. I purchased it because my old one was off by 4 degrees and I wasn’t sure of its accuracy. This thermostat was $25 and is programmable for differing day and night temperatures, which is the feature I like most. It also can be programmed differently on the weekend. I’m hoping the nighttime feature will save some money long term. It is easy to install, just follow the included instructions.

    Poor Quality Control
    I've noticed that this model has varying quality controls: the one I bought previously lasted reliably for years, but the next iteration of the same model often says "Heat On" but fails to engage the boiler, and allows my heat differential to drop several degrees (right now it's 61F in my place, and it's supposed to be 70F). i'm in the middle of New England winter, and some days I wake up shivering and have to huddle in a room with a space heater till the thermostat decides to hail the boiler. Pretty miserable now that I'm at home 24/7 under quarantine. I'm an engineer; I understand sometimes you've got to troubleshoot a product. I've gone through almost every relevant internet resource to try and correct this issue, and I even paid to have a professional come over to look at the thermostat and boiler. I'm on my second replacement, which failed even sooner than the first one (first model started malfunctioning the week after the warrantee expired; Honeywell gave me a replacement, which started showing issues after the first month). Advice: I would look at the form factor of the device: if the text on the front says "Honeywell Home", it's one of the more reliable iterations of this model. If it just says "Honeywell", then good luck. Honeywell used to take pride in their brand, but now they just pass any of my complaints over to Resideo Technologies and wash their hands of the problem.

    Hi Usgan, thank you for taking the time to give us this feedback. If the thermostat is dropping 9 degrees below the indoor temperature without engaging your HVAC system, we recommend checking for voltage and also ensuring that there isn't a schedule that its following as this should not be happening. Please visit our Support Center link at the top of the page lists the ways you can get in touch if this issue persists. We look forward to hearing from you soon. -Jay
      It is cheaper than everything else for a reason
      Both my original purchase and the return replacement had the same very obvious defect in their displays. I returned everything and got my money back. If you're only after functionality and nothing else, this might do it for you (I say "might" because of functional issues other users have encountered). Otherwise, give your money to a company with better QC and save yourself some frustration.

        Manufacturer is Not Inspecting
        I purchased this unit. Opened it up and read the instructions. Labeled the wires from the wall, then removed the old unit. Screwed the new mount to the wall and began to loosen the screws of the wire inputs. Started to insert the wires after loosening the screws; however, the screws for the “R” and “RC” inputs would not loosen. After many tries, I managed to loosen the “RC” input. The “R” would not loosen at all. Tried multiple times, but no success. Returned the unit to the store and exchanged for the same unit. After opening the box, I immediately tried to loosen the “R” screw-would not loosen. Suffice it to say, I will be returning this unit and will look for another manufacturer because I have lost faith in Honeywell when it comes to thermostats.

          Easy to follow instructions
          Replaced a 10 year old digital White Rogers thermostat... Home Depot had all Honeywell.. I picked this one for having the backlighting and week and weekend programmable. Priced approximately only 25.00. Installed in approximately 15 minutes.. works great!

            1. Does not with heat pump system WITH AUX HEAT. I wished it printed bigger on the box 2. Yeah, it is a pain in the rear to remove and change battery. It will pop out with a big head screw driver. IT IS NOT the tab that hold it to tight, it is the electrical PINS. I ripped the unit off the wall trying to remove it. 3. Yeah it can be used, for a $24 it not bad of a value. Just open it, use epoxy and glue all the pieces together minus the base plate. Install using heavy duty anchor just in case someone doesn't know to use a flat head crew driver to remove it... and yank it off the wall by accident. 4. Time is money and I wasted 2 hours on this piece of work...blowing and hunting down my unit's fuse It is a wallet saver. Buy it, use it, but know what you getting into. I will keep mine for experimental projects I have in mind. I wish Honeywell a well established company would not go this low on design, it just ruins the reputation.

              Great value
              Very easy to install and works well. Great value for price. I would recommend for basic programmable thermostat.
