I have tried many bells over the years and they all eventually wear out; however, I do recommend that if you purchase a wireless bell, you purchase one which has a plug in Ding Dong.
This GE 19216 has been in use for a couple of months now and works just fine. I was impressed enough with it to buy a second one for my next door neighbor. It was fun opening up their bell and pulling out one of the little plastic thingies to alter the frequency codes so that our bells do not both ring at once.
Installation is simple and the bells work just fine. I cannot determine the distance that the bells can transmit because both installations are well under 50 feet.
I do recommend this product for its quality and ease of installation. Enjoy your Ding Dong!

I had few problems with this product as soon as it arrived. You can not put this door chime to far from the button control/door. It will still work at 15 feet, but not any further in my apartment. Chime switch is inside the button control. So you have to open it(with something really sharp) to switch a chime tone. It was very inconvenient.
To conclude: product works well under some limitations but was not designed with consumer in mind.

I like it. It was fairly easy to install. I prefer the westminster chime and am having a hard time finding another that I like for the back door. Originally purchased it with one button, then bought the lighted button, sold separately on amazon. I think it looks much better. Seeing the light makes it easy to see at night and gives some assurance that it is functional.
Honest reviews on GE 19216 Wireless Door Chime, Plug In
When I first received the alarm and the optional lighted button, I was fairly pleased with it. But after a few weeks it would only ring about one out of every two pushes. As a few more weeks went by, the odds increased to 1 time out of 10 and then eventually zero. I tried moving the chime as close to the button as possible. Even at 8 feet nothing. I dismounted the button and found that it would work at the stupendous range of 2 feet with no obstructions... most of the time. I tried different codes, no effect. I have an MSEE from Caltech, so I know a bit about electronics circuitry. I disassembled the chime and found that the RF circuit is tuned by a tunable slug inductor. In this day and age of digital VCO's and PLL's, I found it hard to believe that the unit would be based on 1960's technology. I found that the button transmitted at 868 MHz. I started tuning the inductor slug in the chime and found a point where I could just barely get 18 feet range. The temperature in my basement where I tuned the chime, was about 63°F. When I moved the chime back upstairs, where the temperature was about 72°F, the range had again dropped to about 2 feet, indicating that a temperature increase of only 9°F had completely mistuned the chime RF circuit again. What a piece of junk!
So if you still insist on buying this unit, be prepared to do the following;
* Buy a temperature controlled chamber so you can keep the chime at a very tightly controlled temperature, probably ±1°F
* Be prepared to mount the chime less than 2 feet away from the button, preferably not obstructed by any object.
* Better yet, mount the chime directly beside the button, outdoors.
* Print up a nice sign to put on your door that says KNOCK LOUDLY

I had a lot of fun playing with the many different sounds and choosing one. I tested the doorbell near the door to make sure that it wasn't too far from the receiver. Then I attached it to the frame next to the door, following the mounting directions, only to find that it suddenly did not work. Looking at the 'troubleshooting' section of the instructions, I learned that it cannot be mounted on metal. You'd think that this important detail would have been in the main part of the instructions, before one is told to mark the location and to drill holes! My home has aluminum siding, and metal trim around all of the doors. My only option was to mount the doorbell onto the door itself, which is made of wood. As far the bell itself goes: the sound is very tinny.)
