Very Good

Haven't used the transformer as yet - keeping it for future problems. Have installed the two doorbell buttons. I had hoped to swap out the inner mechanism with the old cover (which was spray painted to match house trim) but the two were not compatible. So, went with the nickel finish. Thought the new circuit board was for digital system (marked + & -) but it worked with 16 VAC just fine. In fact the LED on circuit is very bright and easy to see and should last longer than the old incandescent bulb. Had to drill out the **** holes as new screws were bigger in diameter. Am I being too picky? Anyway, I'd buy it again.

Nice looking door bell

Looks nice and arrived timely. Our electrician hasn’t installed it in our new build yet, but I can’t wait to test it out.
