After over one year of using this Thermostat I've very impressed with it. It's been rock solid and stable. It does it job very well and with the right set of SmartApp and my custom Device Handler, I'm completely rocking my place with three of these thermostats.
Particularly with the RBoy Apps updated device handler (community.smartthings.com/t/universal-enhanced-z-wave-lock-and-schlage-lock-and-yale-lock-device-type-with-alarm-control-notification-and-advanced-features/6241) and the battery saver mode enabled, I'm able to get over 18 months of battery life out of this thermostat (that's a 400% increase over my initial assessment). One of the best Z-Wave devices I've bought but it needs the custom device code to get the most out of it.
RBoy Apps have made a ton of SmartApp and Device Handlers for other Z-Wave devices for the SmartThings platform which allow you to make your house your butler. They are available here smartthings.rboyapps.com
I love the fact that with a SmartApp I can make this simple thermostat into a Motion Sensor Based thermostat or a Unlimited programmable thermostat (yes I can 1 or 10 schedules a day and have it turn on only when someone is in the room!). I can link this thermostat to a temperature sensor in a another room essentially with the help of SmartApps I can do what EcoBee does at a fraction of the price and probably a lot more. See my website for ideas and apps on how this can be done. [...]
I absolutely love this. Using this with my SmartThings hub. I initially ordered 1 and so was impressed with it that I ordered 2 more.
Some features require RBoy Apps device handlers
Things to note:
1. It works on battery, but with the C Wire attached it can act as a repeater
2. It reports temperature and relative humidity. However note that the battery life and humidity are not accessible from the SmartThings platform, I've written some code for a custom device type to access it (community.smartthings.com/t/universal-enhanced-z-wave-lock-and-schlage-lock-and-yale-lock-device-type-with-alarm-control-notification-and-advanced-features/6241), so with this feature you can get that also
3. You can't program is thermostat in a normal manner (e.g. 7 day program on the device), it needs a z-wave controller to program it. With some custom apps like the 7 day programmer and extreme program (community.smartthings.com/t/5-2-day-programmable-thermostat-scheduler-weekday-weekend-with-remote-temperature-sensor/6780) on SmartHubs it's a VERY powerful combination. E.g. my smarthings automatically changes the temperate based on whether I'm in teh house or outside (presence sensors)
4. It an AUTO MODE - THIS I LOVE. I hated old thermostats that I had to constantly keep switching between Heat and Cool mode during season changes, this has an all AUTO mode, I can set a range (e.g. between 70 and 75), if it gets cooler than the low point it turns on the heater and if warmer it turns on the compressor. I LOVE THIS.
The battery life is pretty good, after a few weeks it's down by 2%. It has 4 batteries but runs 2 in parallel, so you can change 2 and then the next 2 without losing power to the device.
It is very flexible and supports a very wide variety of HAVC systems from 3 wire to many more wires and types (gas, electric, etc etc).
In all a VERY versatile zwave thermostat.
However Iv'e seen the price of this rise from $80 to almost a $100 in a few weeks in Amazon.
I have an old Trane heat pump system - one with auxiliary and emergency heat. That said, I needed one to - at a minimum - work with the auxiliary heat settings; and one that had z-wave technology so that I could connect it to my security system control panel (and subsequently control the thermostat via my smart phone). For your reference, I'm going to walk you through what I've done and hopefully it's helpful as you do your installation if you have a similar system and thermostat. Do note that there are fairly good resources on various web forums to help you through your installation as well.
My old thermostat wiring (you'll also see a picture of my old thermostat) wires as aligned to new thermostat wires:
G (Green) --- G
O (Orange) --- O
X2 (Black|Grey) --- Tape Off (used for emergency heat - for this thermostat, recommended not to connect emergency heat; fine for me, it costs too much to run emergency heat anyway)
Y (Yellow) --- Y
T (Brown) --- Tape Off (Outdoor sensor - my understanding is that these are not used anymore)
R (Red) --- RH
W (White) --- W
B (Blue) --- C (Note that there are important instructions with the CT100 that details this combination if you have a Trane system - don't ignore that!)
So far, everything is working great. Fairly easy settings, nice push-button and touchscreen format, and nice access via alarm.com (and other sites, as applicable to you).
Lastly, this particular thermostat connects to the wires at the top, so you may need to do some drywall patching/repair if you have large holes left from your old thermostat. I got it all done in probably 6-8 hours, but it did require patching and re-painting (and drying time). The installation itself was pretty easy.
UPDATE: January 22, 2016: So, we're awaiting some bad winter weather shortly, and I wanted to let everyone know that the thermostat has worked great over the last week. The ability to schedule seven (7) days with varying temperatures for ANY hour is quite neat; and I've set the thermostat to adjust for blocks of time for when we're at home and when we're away. I LOVE not having to constantly adjust it before I leave, before bed, etc.
UPDATE: May 18, 2016: I moved from my previous home where the original thermostat was installed. And, we just bought another one to put in our new place. Yeah, it's a really nice thermostat and I love the ability to create variable daily schedules based on wake-up times and other factors via the website or smart phone.
UPDATE: June 1, 2016: The second one is installed that I referenced on 18 May. It works perfectly. The wiring was a little different this time, but still a Trane heat pump, and it does the job.
I am just happy to have a thermostat that I can easily program through a zwave hub and interact with my other devices. It's also nice to use presence for setting the temperature. The Nest was very appealing to me as well, but would not work in my home due to not having a c wire. This thermostat can do everything Nest can do, but may require more effort. It is also a lot cheaper than Nest.

I have it working with my Smarthings system, you won't find a Z-Wave thermostat even close to this price on the market.
