Wireless Door Bell, CW-12 Mini Waterproof Doorbell Chime Operating at 1000 Feet with 52 Melodies, 5 Volume Levels & LED Flash

I love this doorbell!!! I did a lot of research and there are a lot of doorbells out there that you can plug in but all of the others will take up both outlets (at least this was the only one I found with 1 transmitter and 2 receivers). It is more expensive but worth it to me since I can use the other outlet (since I have 2 receivers would mean I would have lost 2 power outlets completely). This model comes with 2 receivers - I have one on each floor and I can finally hear the doorbell when I am upstairs. Was very easy to pair the receivers and transmitter - I was concerned about that but not an issue at all. The tone I have chose is loud enough. I like the fact that you can switch the sound off completely if you need to (has a few loudness options). Cons: The only con I would say is that it says it comes with 52 chimes, but there are only a couple that I consider actual doorbell sounds. I takes quite a bit of time to find a decent tone and I had to do that for both receivers. However that was a minor con since there are so many pros.

El timbre es bastante funcional en su instalación, ya cuenta con pila, está muy bonito y estético. Tiene excelente alcance y bonito sonido .

Me gustó que se puede ajustar el volumen en las 2 terminales que trae

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.

Easy to set up.
