4 years and still working with the same batteries!
Color: Black
When we moved in, the doorbells did not work and it wasn't going to be a quick fix. I ordered this set because we have a side and front door that both needed a doorbell. You can set the doorbell tone to different sounds so that you know which door has been rung. It has been 4 years and 7 months since we purchased these and they are still working great with out any battery changes. One is more exposed to the elements than they other, but there have been no issues with either. I paid $22.99 and I am extremely pleased with my purchase. I highly recommend.

Compact size does not interfere with other outlet
Color: Black
Like the compact size of the receiver as it allows for both the 2nd outlet to be accessed when the receiver is plugged in. The volume settings could be more adjustable - I found it difficult to find a happy medium between too loud and not loud enough. The instructions for pairing multiple transmitters and receivers (in my case, 2 transmitters and 2 receivers) SHOULD be written better/clearer/more detailed. It was difficult to understand how to get both receivers to ring at the same time with different tones for the front door transmitter and the back door transmitter...but after some trial/ and error I finally got it programmed. Way too many weird ringtones - would prefer more normal doorbell tones to choose from but I landed on two that worked for me. So far, so good - now to see how well the transmitters hold up outside - then I can rate the "weatherproof" aspect.

Outside doorbell
Color: White
Easy to install and works great. Outside in the weather and no problems

Very convenient
Color: White
Easy to install, works great. The old one that I had did not have the picture of a bell on the button, so people didn't always realize I had a doorbell. They see this one, so they actually ring it instead of knocking. I recommend it.

Ding Dong Done Easy

Loved how easy it was to install. I just wish I had a list of the tunes in the order they were programmed.

Best Doorbell dual buttons
Color: Black
Our driveway is 572 ft. long. We placed one doorbell on top of the iron gate keypad People can ring that doorbell, with its unique tune, to announce their present and gate needs opened. GOOD RANGE. Horse farm workers come to house and ring that doorbell with its unique tune and I know to go to door. TWO UNIQUE DOORBELLS are efficient.
