Customer Ratings & Reviews

Had to get the c wire adapter for the amazon thermostat. It was fairly easy to install, just need to follow the instructions and color wires thoroughly.

Best Buy is my favorite store for everything with free shipping and easy checkout..

works great, easy to install and operate. good upgrade

Easy to install, installation instructions are accurate

For whatever reason the Honeywell thermostat that I purchased stated it came with this adapter and when I got home and opened the box this piece was no where to be found. Their website will ship one for free but takes nearly a week, so I opted to purchase this through Best Buy. I am not one to install things myself but the directions were very easy to follow and saved me a lot of time and money by not having to pay anyone to come out and install the thermostat.

My review is based on price and shiping. Excellant anmd quick shipping but never opened so i dont know how it works. unfortunately, I could not use this item. I have an oil heating system and it is not compatable by which i mean, it will cost me hundreds to have this one piece installed on to my heating unit which i was told would need wires modified to it. This is not an simple attach to wires type of thing and I reccomend you speaking to a professional before purchasing or be stuck with something that now cant be used and its too late to return.

It works………………………………………………………………………………………………………………

Works perfectly and easy to install. It allowed me to use a Wi-Fi thermostat in an old house that lacked the modern wiring.

I bouth this c-wire and it was so easy to install, and I definitely recommend this to family and friends whoever needs to install a alexa smart thermostat..

Works as expected but the instructions were confusing. After I installed it I had to take it apart and do it the opposite way.

Works great if you need it to connect thermostat to unit.

Easy to follow instructions and works great for our new HVAC system

Worked as they said it would. The part was needed.

I rated it as 3, as I believed it should be easy to build in a device within the thermostat. It looks strange to have an external adapter outside the thermostat and just for generating a C wire from other 4 wires.

This worked perfect for my thermostat! I needed this to help give power to my new smart thermostat and this did just the trick! I’m glad this was suggested at checkout because I definitely needed it!

I got this as I was warned I might need it with smart Amazon thermostat but turned out I didn't so returned it but it was cheap and maybe you'll need one?

Needed for the Amazon Thermostat. Fairly simple to install if you have good access to your Furnace. I have a furnace that is over 20 years old and didn't have a C-wire. Just had to match up the color wires to the right terminals.

Pretty good quality, for the price, compatible with Honeywell thermostat

[Employee of bestbuy] Works as advertised super easy setup video walked you through it

Well built. Solved the C wire issue. Not easy to install
