Install it on your first try or throw it in the garbage

If you are a master in aligning a temper glass this product is for you. Otherwise, you will waste your money. After failing to align the first time, I tried taking it out a little bit to align a corner but it attracted all the dust and it was impossible to clean it without destroying it. Now is in the garbage. After this incident I looked online for solutions and it seems there are multiple temper glasses there that can be cleaned with alcohol napkins (found in any supermarket) or your usual glasses cleaning solutions, and reused. Look on YouTube. For this product is not the case. I told the producer my frustration and he offered me a 10% discount to buy a new one but  I won't buy a second item just to make the same mistake.

I made the terrible mistake of buying this garbage directly from Belkin, on sale.  So you set it up, and you immediately realize how garbage the software is.  First it had trouble getting into my wifi router.  Then when that worked (after a couple crashes), I set it up on one light bulb as an experiment.  The app immediately started downloading firmware update after firmware update after firmware update.  Then after it seemed like that was all done, I added the second bulb.  It promptly started doing ANOTHER firmware update, and then forgot the first bulb.  I have thus far been unable to get it to recognize the first bulb again.

This is, in short, totally hopeless.  It's like setting your money on fire.

Why? because if someone tried to install it and then return it, it will not work. I spoke to ismartalarm tech and that is what they told me. they told me to return it. the only way to reset it is the original buyer must remove it via software from their system.
DO NOT BUY THIS ITEM USED.

Awful product, poor instructions - advises to download generic drivers which did not work (and take about 1hr to install heaps of bloated crap on your system), downloaded drivers from manufacturers website and got it working once out of four attempts. Google searches and forums suggest multiple restarts, reinstall - this isn't 1998, things should work 100% every time rather than require this kind of trial and error garbage. Don't buy this junk and add to the bottom line of companies that push crappy products out. Expensive considering it doesn't work, and will only waste your valuable time.

Watch a youtube video on installation first. It seems easy until you get to that rubber thingy and if you put it on wrong you'll spend two hours trying to install the unit until you realize it's not supposed to go up that far (the rubber thingy). It works great and runs pretty quietly.

Attempted to install first time around and wasn't able to thread the new screws.  Took another shot at and figured out that if you applied pressure on the grab bar towards the windshield the side screw will align properly.  The difficulty might be relieved if the new screws matched the stock screws they were replacing.  See photo.  I also wasn't impressed with the spacers because while they sit flush against the bar, it appears awkward with the metal spacers on metal bar.  See photo.  Lastly, the instructions were littered with the typical typos and grammatical errors of a Chinese made product.

This thermostat shows all of the signs of having been created by pretty good engineers and horribly incompetent product managers. Even if you follow every single step provided in the Quick Start Guide, you probably won't get the thermostat to power up. Without the help of my fellow reviewers here on Amazon, you will not be able to get the wireless connection and registration to work. Period. I don't believe they did much usability testing for the installation process of this product. Really, it's that bad.

I spent four hours last night, up and down from the attic and fiddling with wires until my fingers bled. I gave up and reinstalled my old thermostat so that we wouldn't freeze overnight. Reading the reviews here, I learned the following bits of guidance that you should follow as well:

(1) You absolutely need the C wire. There are no alternate wiring plans that will help you avoid this. You must connect the Common 24V wire, usually an unused wire in the bundled cable, from your furnace controller board to the thermostat. You can connect multiple wires to each contact on the furnace controller board. In fact, you'll have to do this with the C wire if you already have an air conditioner installed. Once you connect the C wire, the thermostat will have power.

(2) You need to make the base plate of the thermostat absolutely flush with the wall. I suggest countersinking the drywall anchors because the back of the base plate does not accommodate the 3mm protrusion of the anchors, and your thermostat will be rocking and wobbling all over. Screw it down tightly.

(3) Set the date and time as soon as the thermostat powers up. You'll get into trouble and have to reset the wireless settings device if you don't do this first. You just don't want to go there.

(4) The wireless connectivity setup is a tightrope walk, juggling burning torches and bowling ball. Read the advice here and watch the ENTIRE video on the Honeywell site before you try to do it. You will fail miserably if you try to follow along, step by step, because you will lose access to the video instructions along the way. You'll need to set your router to WPA2-only security and heed the warnings here about network naming. Your thermostat will time-out if you haven't mastered the process as well as the engineers who built the device. You'll need to pop it back off the wall, hold it for a minute, and then reattach to the base plate to get your web browser to recognize it. If you make any mistakes along the way, you will pay dearly. You really need to know exactly what you're doing so that you can make the right responses at the right times.

Once you're installed, connected, and registered, you can start to get into the scheduling process. So far, that's been unavailable to me, but I've learned a lot about the inner workings of the Honeywell engineers' minds. With patience and a healthy dose of web research, I think I'll get scheduling to work soon. Best of luck!

Gave it a shot, didn't get my hopes up and sure enough it was junk, DOA, should have stuck with my first instincts

Broke during installation. It's a piece of crap.

I tried to use it, too weak, too cheap and not worth it.
I threw it away after 3 min of installation.
Smple as that. Didnt even bother to get a refund.

Mine was the same experience as most others, failed immediately out of the box.  Unfortunately, I waited a while to install it, and it was beyond the return date for Amazon.  I also didn't read the reviews before purchasing, probably wouldn't have done so.  2 strikes against me...

These are junk and go out shortly after install and need replaced again. Buy quality the first time and save yourself the trouble. Don't mess with this crap
