Getting this to work required multiple tries, but no real reason why it wasn't detectable by the Nest thermostat. However, the physical installation was a lot easier.

It works wonderful. Never trouble after it got instay!

I watched the video on YouTube and read the directions thoroughly prior to installing. Installation was straight forward and easy. My Nest Learning thermostat was showing low battery every other day. The wi-fi would also disconnect. I wound have to pull it off the wall and charge it. I installed the Nest Power connector and the low battery issues have completely stopped.

Not sure how this was supposed to work. It didn't fix my issue of my nest thermostat not charging properly. I had to install a new thermostat wire for my nest thermostat to work.

Don’t waste your money. This product does not work as intended. I hooked it up as instructed and still had issues with the battery on a new Google nest thermostat. I called Google and they were unable to assist — they haven’t been trained on this product. Additionally, if you own a 3rd generation learning thermostat, there’s no functionality to check to see if the power connector is actually installed. So, today I just used the extra blue wire that was not connected to my furnace board and wired it as a c wire. There’s plenty of YouTube videos showing how this is done.
