    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.

    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.

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

    A necessary device ?

    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.

    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.
