Customers like the ease of installation of the HVAC control thermostat. For example, they mention that the connectivity is easy, programming is easy and the app works well. Some appreciate the simple and responsive design. That said, most are happy with the ease and functionality of the product.

Customers are mixed about the quality of the HVAC control thermostat. Some mention that it's awesome, they really like the settings and all the options, and they're able to control the heat for specific rooms with this thermostat. They also love the adjustable temperature remotely, and the crossover temp is easily adjustable from the installer menu. However, others say that it failed and started sending voltage, had poor heating, and wouldn't switch to cool. The default from the factory does not work for a heat pump, and it'll not measure the bedroom temperature.

Customers are mixed about the performance of the HVAC control thermostat.

Customers are mixed about the app. Some mention that they love the Honeywell app and it's integrated into their Samsung Smartthings app. They also say the thermostat and sensor is a nice addition to an automated home. However, others say that the Resideo app is by no means great, highly convoluted, and glitchy.

"Had on/off again issues with this termostat until it showed an ‘internal sensor error’. Not sure how to fix. Would not buy again." Read more
Customers are dissatisfied with the stability of the thermostat. They mention that it won't stay online, it drops the internet connection occasionally, and it sends 5-6 offline alerts daily. The app logs them out too often and the WiFi stopped working after 3 months.

So, the same thing started happening a few days into my replacement (new) T10 thermostat. Fortunately, I had done enough research, troubleshooting, and had a couple of cheap furnace parts on hand, and, fingers crossed, it may have been a flaky pressure switch on my inducer motor that was causing the issues. It was just a coincidence that changing out the original T10 for a basic non programmable t-stat "seemed" to cure the issue. Time will tell, but if this thing continues to work, it's fantastic, and hands down, better than Ecobee's latest 2022 Premium, IMO.

---end of update
I really wanted to like this thermostat, as I have always had Honeywell t-stats in the past. I was warned that the T10 had to be installed by a "professional" in order to have ANY warranty whatsoever, whereas the T9 is approved for installation by the homeowner. Honestly, other than additional features, the installation process is virtually identical, so I don't understand this distinction. I ordered the unit in Sept of '22, and installed immediately. I wanted the T10, as I had also purchased a Honeywell HM750 whole house steam humidifier, and it is one of the few t-stats that can control a steam humidifier. Well, as summer transitioned into fall, the t-stat appeared to work great! However, once the temps dropped consistently enough to require full time heat setting, it began to fail. I honestly thought it was my furnace that was failing, as half the time, the ignitor and gas valve failed to activate, even though the inducer seemed to run fine. I was chasing down pressure switches, ignitors, and even the IFC main furnace board! No improvement. However, bypassing the T-stat at the IFC directly, the furnace ran fine! This was not a solution, as I couldn't sit in front of my furnace 24x7 to control it manually every day. Ultimately, I went to a local box store and bought the cheapest basic thermostat I could find, and plugged that in, and the system has been running great! Unfortunately, I can't control my fancy steam humidifier, and had to resort to using the included humidiPro. Through an independent HVAC specialist, who came out and assisted me in this project, I was able to ultimately get a replacement ticket initiated through Resideo, however, I am awaiting acknowledgement of the required attachments I sent them, verifying my purchase and the device info.
Currently, I am using an Ecobee Premium. By comparison, I find it's app highly convoluted, and it takes considerable focus to find what I need. Also, there is no "circulate" function on the Ecobee, whereas there is on the T10. The Resideo app is by no means great, as it must be force closed to get the latest data from the T10 every time you make a change, but it's simple and concise to use. They just need to update it so it will refresh in the background, and not require a force close each time you pull it back up.
Also, I prefer the functionality of the Honeywell remote sensors over the Ecobee sensors because the Honeywell pull both Temp AND Humidity, along with motion activity, whereas the Ecobee sensors do NOT pull humidity! I want both temperature AND humidity levels balanced! There is no reason for Ecobee to not include this in their remote sensors....
I will update this review once I get some action on my RMA process.
It is working great! Very easy to install - make sure you have a "C" wire. I have a simple forced air gas heat and A/C system, but the T10 can handle much more complicated systems (heat pump, humidifier, etc). I really liked the over sized trim panel that covered the unpainted part of the wall behind my older, larger thermostat.
My problem was the second floor of my house - all the rooms up there had temps that would widely swing depending on how sunny it was (rooms on the west side got very hot in the Houston sun), if the doors were open/closed, etc. The thermostat was in the hall so quite often the temperature in the hall was very different than the temperatures in the rooms.
When I ordered the T10 I bought additional temperature sensors for all 4 rooms upstairs, paired them with the T10 and now all the rooms are very comfortable. For each schedule you can designate which rooms have "priority", meaning which rooms the T10 will use to turn the A/C or heat on/off. So during the day, the rooms used for study/work have priority and their temperature is controlled and the unoccupied bedrooms don't impact the cooling/heating cycles. At night the reverse is true - the bedroom temperatures are maintained and the other rooms just float.
The iPhone app works very well - simple and responsive. I did not have any issues, unlike a couple of reviews I read.
I'm very happy with the purchase and I plan to buy another one for the downstairs. With all of us home every day during this COVID stuff, its really nice to have the house comfortable for everyone.
