## Customer Reviews

### ⭐⭐⭐⭐⭐ easy install and works great
*by A***T on July 10, 2025*

easy install and powers my Google doorbell well

### ⭐⭐⭐⭐⭐ Ring Compatible, Easy Installation! Excellent Power Output!
*by K***. on May 6, 2025*

Purchased this to increase power to my Ring doorbell Pro. Even though my house is only two years old the16V transformer was inadequate. In the Ring app, it said my power output was level 2. Just enough to keep it powered, but not adequate to make my doorbell chime work when the button was pushed. I also know that the old transformer was very hot when I took it off meaning it was being overworked.Now since I installed this new one, I’m at level one power output, and my doorbell chime works loud and clear. Actually better than it did before.The only negative thing I have to say about this product, the mount on the transformer was bent pretty badly. But I used the wiring port to screw it to a face plate instead so I didn’t need the four screw mount.Great product, easy to install size is typical for a transformer like this. Definitely Ring compatible and I recommend it..

### ⭐⭐⭐⭐⭐ Works Great for Video Doorbells
*by O***S on June 8, 2025*

Provides the power needed to run my video doorbells. Used as a replacement for a less powerful transformer that didn't meet power requirements.
