I used this to replace an older wireless doorbell. Main reasons for replacing the older unit were that it was not really loud enough, and had only one chime unit. The new one I ordered came with two chime units.I plugged in one of the chime units high on a balconyl above some picture frames, and followed the instructions to enable the battery on the doorbell button. When I pressed the button, I immediately heard the traditional "ding-dong" sound from the chime at a perfect volume level. I may experiment with other sounds, but this is the one I am used to. Later I moved this receiver to a Bluetti EP500 in the kitchen which keeps my refrigerator running during power outages (in the picture, the chime is hidden behind an orange extension cord).I then plugged in the second chime in the basement, where it is hard to hear the first one. It also responded to the doorbell without needing any further adjustment.The only slight inconvenience was that button did not have pre-drilled holes for mounting, and I preferred to mount it with screws. But that was easily solved with an electric drill. Although that could be a drawback, I don't consider it serious enough to affect the overall rating since an adhesive mounting is also provided.To enable the doorbell to work during a power outage, I plugged one of the receivers into a Bluetti EP500 which also powers my refrigerator. In the picture, it is partly hidden behind an orange extension cord.

Has many preprogrammed songs! Even for the holidays! Very loud when adjusted to max. volume! Super easy to install and program!

I love this doorbell it chimes well and is loud, you can turn the volume down but I left it the way it was as my hearing isn't that good, I would recommend it as you do not have to drill any holes just plug it in, and being a senior it works perfectly for me.

This product is well designed & is easy to install. I chose the 2 doorbell model, & it was simple to select which chime I wanted for each door. There is large selection of tones, some louder than others, so you will find several that you like. I like that it was well made but inexpensive, it has held up well through lots of weather, & the buttons are large & easy to find in any lighting. The power unit is also compact. I am really happy with my purchase.

We purchased a set of these a couple years ago and they have held up really well. We recently decided to use one in an elders room so they could ring us for help. What a great idea. The doorbell button is the perfect size to use as a necklace pendent or bedside button and setting the ring to something we associate to them has made it easy for all.

Incredible sound in terms of quality and decibel. The highest volume can probably be heard from the moon, so if you're hard of hearing or work in a barn a mile away, you'll STILL hear this doorbell on the highest setting. I'm being hyperbolic but only 90%.So many songs and alerts to choose from, it's daunting but fun. Every time I thought I had chosen one I'd click a few more just to hear a few more options then I'd have a new favorite. Some of the sounds are hilariously distinct and something I'd never actually want to use as a doorbell but I'm also half inspired to use the ridiculous ones simply for that reason.Easy to put into place, easy to figure out, aesthetically pleasing, and did I mention it's loud enough to be heard during a demolition derby? It probably is.I got two doorbells so I'm splitting my sounds up - one normal doorbell with a pretty song (I'll probably go with Fur Elise) at one of the lower volumes and then a secret doorbell near the real one but out of sight a bit for people I KNOW and LIKE to ring, that way I'll always know whether it's someone I want to see or someone I wasn't expecting. The friend-doorbell sends a rooster crow sound through the whole neighborhood when it goes off. I laugh everytime.
