Rated 1 out of 5 by Burned out after two weeks Must have gotten a bad one. Got another one from a different location, and seems to be working OK. December 10, 2014
Rated 3 out of 5 by short life span This transformer only lasted (worked) for about a month then it stopped working. I had to give up on wired and go to wireless November 5, 2014
Rated 5 out of 5 by Plenty of power This was the perfect transformer for my basement water detector project. October 7, 2014
Rated 5 out of 5 by Works great! My chime works properly now! I bought this to replace an ancient NuTone transformer. The old one worked fine, but my chime specified 16 volts. The old tansformer was 10 volts (the home builder installed the wrong voltage). It was very easy to replace, just make sure you turn off the power. It works great with my 55 year old NuTone chime and my 10 year old lighted button! August 22, 2014
Rated 5 out of 5 by Easy to install and works great I had no experience in replacing a doorbell transformer but this one was no problem to install and fixed my problems with my doorbell. February 1, 2012
