Rated 4 out of 5 by 5 reviewers.
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
Rated 4 out of 5 by Product quality was not what I expected. I was happy with the outcome as the product worked once installed. January 26, 2014
