Rated 3.3 out of 5 by 6 reviewers.
Rated 1.0 out of 5.0 by Does not mount securely This transformer uses a quick-mount set screw rather than a lock nut. As a result, it did not mount securely in a 1/2" knockout in a steel 4" box, 2 1/8" deep. In a standard 4" box that is 1.5" deep, it wasn't much better. I will try to return the opened package and will look for one with a lock nut. February 15, 2015
Rated 5.0 out of 5.0 by Easy Install This item had clear instructions and ease of installation. It appears to be well made and worked perfectly. February 25, 2014
Rated 2.0 out of 5.0 by Audible Hum Put it in my wall and then found out it had an audible hum to it. I'm going to trash it. Otherwise, it worked fine. January 17, 2012
Rated 5.0 out of 5.0 by Good if you know where to put it. Absolutely a perfect replacement product for many types of doorbells and hvac equipment. Often times magnetic transformers have a little hum, knowing this I placed the junction box on a block wall located under my house and pulled power from the porcelain task lighting, it works perfectly and no hum unless your hanging out in the crawl - who does that?

Rated 2.0 out of 5.0 by what is that sound? Bought at a local Home depot store. Was not sure about wireless doorbells due to lots of other wireless doorbells in the area. Went wired. Installation was fine, but.....what.....I can that a audible HUM in the hallway where I installed it. Nothing I could do about it. I guess I can just hum a new tune each day.... :( July 23, 2013
Rated 5.0 out of 5.0 by best solution when your transformer burns out works well, easy install, don't get confused between the 24,16 and 8V. This also works well as replacement for HVAC 110-24V transformer August 19, 2014
