Rated 5.0 out of 5.0 by CK42 So much better than my old one.
I got it just in time to make my life easier during the Fall changeable weather. It got hot, then cold, and the thermostat just worked, changing from heat to cool as needed. One thing, though, you need to download the latest version of the manual, and throw away the one that comes in the box. It is probably too out of date to be useful.

Rated 5.0 out of 5.0 by Justin Relatively simple wifi-connected thermostat with mechanical relays
While looking for a solution to the cooling issues in our townhouse (namely the 3rd floor is too hot, second floor is fine, and first floor gets cooler), I was originally looking towards a Nest or Ecobee3. However those thermostats apparently have some reliability issues as they don't use mechanical relays and instead use FETs to flip heat/cooling online. So I was originally going to stay with my Honeywell 6300 non-wifi unit. Until I was up with the baby in the nursery roasting one evening and had enough.
This unit requires a C-wire which my old thermostat didn't use, however I did actually have the wire. If you don't have one, you'll probably eventually need one for any smart thermostat. Your options are to run a new wire/set of wiring or you could use a Venstar Add-A-Wire which would give you the extra wire for C.
Since I was replacing the 6300 with this guy, installation was easy. Flip off the breaker, remove the old thermostat and bracket, install the new bracket (which even used the same screw locations) and add in the wires. Importantly adding in the C wire to get this guy power.
You flip the breakers back on, and then I was basically back where I started with a dumb programable thermostat. The thermostat starts up a wireless access point you can connect your laptop or phone to and add in your wifi connection details. Once it has that, it'll reboot and connect to wifi and the internet. You then have to register with Honeywell's site and register the thermostat. As other mentioned, at that point, it'll do a firmware update. Finally you can go onto honeywell's site and run through a wizard to program your programable thermostat. It'll ask you questions and build a schedule for you and then ask you if you want to load it into the thermostat. So, that's probably the most detailed, easiest schedule I've ever programmed into a thermostat.
I originally got this as I wanted to be able to change the temperature from my phone (which I can) but since I programed a decent schedule I don't really have to. I bring the temperature down at bedtime which cools the 3rd floor down.
This really costs about $20 more than the 7-day programable thermostat and as long as you can get a C-wire hooked up, I think that's worth it just to be able to use the website to program it instead of flipping through buttons. It's so much faster.

Rated 4.0 out of 5.0 by Homeowner Good product
Great product but beware if trying to claim any energy rebates as they are only valid if installed along with a new furnace or boiler as part of a complete heating system replacement.
Very small print at the bottom of the rebate form.

Rated 5.0 out of 5.0 by Ryobi1 Worth every penny!
Works exactly as described! It is set to run a program, but if you leave the house for the afternoon and forget to turn back -you can do so right from your phone..anywhere! On multiple occasions I have been working around the house and get too warm but do not want to take the the time to run upstairs (or down) to turn the heat down, so I just pull out my phone and adjust. Also adjusting the programming schedule from the comfort of bed on the iPad -very nice. Great product and worth the extra money over the cost of a standard thermostat!

Rated 5.0 out of 5.0 by Rumen Excellent product
I have this item for about 6 weeks now and never had issues with it. It lost Wi-Fi once and it was when we lost power. It is a very reliable thermostat. Even though it has Wi-Fi and you could use it online, it still has the programming features like a normal thermostat and these could be used as a plan B if you live in an area where losing power is not so uncommon.
App is a little slow but very reliable as well.
Overall, this is a great product.

Rated 5.0 out of 5.0 Worth every penny
At first I was hesitant to spend this much money on a thermostat, but in the end it was 100% worth it. I have COMPLETE control over the heating and cooling in my home now. You can dial it in by 15 minute increments any day of the week.
My frustration with older models is that everything has to be done on the unit itself. This involved pushing a lot of buttons and trying to read small type on a greenish yellow backlight. Because of the WI-FI capability on this unit you do all the programming on your computer!
The other great thing is that between the printed guides and videos you watch online, installation was very simple. This is a fantastic product that I would recommend to anyone.

Rated 5.0 out of 5.0 by lp2k Not for the beginner installer
This is my first review. We bought this thermostat for our new house. Easy to install wiring wise, has the openings and labeling. Also came with stickers to help label the old wires. We had a digital and decided this is good for us since its programmable and also has wifi. What I didn't know was that you do have to toggle the proper function on the unit by pressing the up button and another to set the internal function. For my Florida home, it was 2-0. I highly recommend learning what each wire on your thermostat does, like the Green wire really does turn on the fan and it is correct. I had an Orange wire which means not only do I have a heat pump system but also that I had to tell the thermostat that or else it will blow hot air instead of cold air. I did take photos of my install, and it does level nicely. The app is easy to install and hooking the t-stat to the router for wifi was easy. I def did read a lot online about t-stat wires and what they do.

Rated 2.0 out of 5.0 by Adam bill went up 28% on average
The WiFi and everything works fine, Problem is the way it handles the temperature. This model if set at 72 will cool to 71 then wait for temperature to raise back to 72 then start cooling again. unlike most thermostats if set to 72 it will cool to 71 and wait till the temp is 73 then start cooling. this is to save energy and wear and tear on your equipment. The same thing happens even in heat mode. you get a tight 2 degree swing not the standard 3 degree swing. Why is this a problem? for me I don't like the fact that my electric bill has jumped 28% and the constant turning on and off of my HVAC system. 1 deg of comfort is not worth it, So I'll be putting my old one back on the wall until I can find a WiFi with the 3 degree difference.
I have used this Thermostat for 4 months now and it would have gotten a high 4 maybe even a 5 star rating if it were not for the cycling issue and Honeywell knows of this problem and has no plans to update the software to correct it. WiFi and all have worked fine.
