  • Well worth the money, easy to install and works great!
The actual installation took less than 5 minutes. You do have to unscrew the mounting bracket feom the wall and weave the chord behind it and out, but it was super easy to do. I was so excited to get it hooked up that I just did a temporary install for now, running the power chord under my door and over to an inside outlet. Once I have a little more time I will hook it all up with the clips I bought. Works just fine for now though :) I am so happy to not have to deal with charging the Ring doorbell ever again, especially with winter coming. I was not looking forward to fiddling with the security screws in the cold. Chord length is a super plus too. Easy to trim down if it's too long, but I doubt it will be necessary for my install. ... show more

  • It works and I can use my thermostat
Have a ecobee thermostat with no C wire hookup. Grabbed this and installed it to do the job. Long wires, easy install, and works the thermostat just fine. I would highly suggest grabbing one if you have no c wire.

  • Long cord is a plus
Worked for my video doorbell installation. I went this route so i didn’t have to mess with batteries since I didn’t have an existing doorbell.

  • Excellent purchase
So easy to install, I was planning to buy a small transformer for my Ring camera, but this was the fastest and easy way to do it.

  • A waste
This is not compatible with my Nest Thermostat despite what I seemed to be reading. It came in a box with no instructions. I put it into the C wire slot - there were two thin wires that did not separate - and they wouldn’t go in. So I tried to get them to act as one wire and they did not. They were too thin to register as being in the slot. When I did get it to sit right, I couldn’t get the cover back on. So I did try to fish it behind the plate, but one of the wires fully snapped off. I don’t even know what to do with the damn thing now. I’ll just keep replacing my batteries and having Google yell at me about my C wire. ... show more

  • works great with Gen 3 Nest thermostat Beats running new wire
I have oil baseboard oil head and air-conditioning. Here is what you need to do. shut off system at electrical box. both compressor and air handler. put one wire to "C" and the other to "RC". plug the unit in, turn the system back on. I would suggest if your battery is low, to charge the nest a little bit before turning everything back on. I have not seen a drop in charge since I have put this transformer in. ... show more
