RDWL311A2000 Series 3 Doorbell Portable Wireless Doorbell & Push Button

Lo bueno: es fácil de instalar, colgar (con cinta doble cara) y de operar. La marca es inmejorable y la calidad indiscutible. Lo malo: solo tiene 4 tonos, no se le pueden agregar más, y no tiene control de volumen (¡es altísimo!). Tiene varias funciones interesantes que no he explorado, como el "secret knock" así que por lo poquito que pagas te llevas mucho. Lo portátil es un plus aunque tengas que usar baterías. Hasta ahora me han durado un mes sin problema.

I bought this for my 92 year old mother for Christmas as her previous doorbell stopped working and she couldn't hear anyone knocking on the door. (Right beside her chair!). I was hesitant as I wasn't sure it was going to be loud enough for her, but it is. It's loud and clear even with the TV blaring. It's very compact with it fitting in your hand. (Much smaller than expected, but don't let the size fool you.) It couldn't be any easier to set up and she's thrilled with this awesome doorbell. I hope it lasts for a long time. (The previous one of another brand only lasted a little over a year.) I highly recommend this doorbell.

I love this doorbell. You can use it as a portable or mount it on the wall. I mounted mine up high in my front hallway and it is loud enough to hear in my bedroom (my apartment is 1100 sq.ft.). The size is small, so it is less obtrusive. I purchased a second pushbutton for my back door. The only 'glich' I had in the installation was that the bell does not work through a brick wall, so I had to mount it on my screen door in the back, and then it worked fine. The front door pushbutton was mounted on the door frame. The pushbuttons feel sturdy when pressed. It was easy to set up. I used the chimes for the front door and the bell sound for the rear.

Buen sonido y buen alcance, el único detalle es que el volumen es fijo y no se puede modular, además de que solo tiene un tono, por todo lo demás es resistente y funcional mejor que otros timbres que he tenido.

If this was any easier it would have installed itself. This is a well made unit. Easy to set up, hang up and select the lighting and song. Volume is great and selection of tunes is perfect. I chose the saxophone music. Very impressed with this. The bell push comes with a battery and the main unit needs 4 C batteries.
