Wireless Doorbell, Coolqiya Door Bell Chimes Kit with 3 Plugin Receivers and 2 Remote Waterproof Push Buttons, Operating Range Up to 1000 Feet, 58 Melodies and 5 Volume Levels, LED Flash, White

I love this door bell you can apply it to your house easily and only takes a couple of minutes. Arrived in mint condition as described and we love having a way to hear when someone is at the front and our back door. It has 52 different rings but mine is just ding dong! Both doors as my parents are elderly and they get confused with to many new techie things to deal with so I left ring tones easy for them. They like to watch tv in different parts of the house and my dad is hearing impaired so he never hears our regular door bell. This one I set much louder and now he knows when someone is at the door. He used to miss a lot of deliveries and friends who would POUND on the door or windows to get his attention. Now he hears the door bell. My Mom likes to be in her sitting room in the master bedroom to watch her tv and she never hears the door bell, now she does as I placed the plug in device in the hall way off from the kitchen and launtry room. Now she can hear when people are at front or side door. I am in my office and I can now hear the door bell from the back of the house and I can see who is at our slider, side door or front door. I should have made each door bell a different sound but they get confused with which door to go to, now they check which door they are closest to and if nobody there they go over to the other one if all our shades are closed. Great working device and so easy to apply I did mine without screws and just stuck them on the house siding out of the weather. Arrived quickly and in mint condition. Telling my neighbors and friends how much difference these door bells have made for all of us.We don't miss our UPS or postal carrier or neighbors or friends who come by to visit or drop off packages. I wish I had known about these sooner and how simple it was to set them up. Saves us a lot of hassle now.

Pros: Easy to set up, works as advertised, has at least one song / sound that you will find acceptable out of the 50 plus loaded into the unit. This is not going to sound like a Bose system but it does the job. If you are patient, it does not take long to figure out how it works. I placed this in my mother's three-story townhouse; she is 87 and hard of hearing. Needed something she could hear with her hearing aids in or out. Placed one on each floor. Set the back door to play one sound and the front door to pay another so she knows what door to answer.Cons: The doorbell button uses a battery that may be a little difficult to locate locally but you should be able to get them online easily. If you have a metal wall plate the bell will not work, either replace the plate with a plastic one or use another outlet. These plug into the wall so if they are in the open small children may want to play with them, which can change the settings or cause problems that are more serious when the child tries to take them out of the wall. No firsthand experience here, just doing a little risk management. When the wall unit rings blue lights flash, which may attract small children. So location is a consideration. While these are loud, I wish they had one or two more settings to increase the volume. I do not think if she is sleeping without the hearing aids in she will hear the doorbell. I have a similar object in her bedroom for the telephone and it is louder and does wake her from her sleep. That said I am pleased with size, cost, appearance, ease of installation and recommend them. BA's husband Tod

First, I like this product. It is a good product. Tone is acceptable, I like no batteries in the main units. Well made and looks good. I like the subtle light for the hearing impaired.However, the instruction translation has issues and are quite frankly incomplete. But good value if you are clever and willing to "manipulate your environment."You receive 3 receivers and two buttons. But it is not obvious or covered in the instructions how to take full advantage of the units. Also, I had problems with the second button (sender) unit activating the other receivers.So:1.) Follow what you can read as the instructions are fair.2.) But, don't wait until a trouble shooting session to "de-program" the receivers . Right out of the box, you should hold down the ring tone button in the down position until you get an alert which will remove any other previous programing that the unit received. This will save you a lot of hair pulling.3. Pairing of the button with the receiver directions seems to imply that one button is paired with one receiver. So you might follow the path of paring the front door button with one receiver and chime selection and the back door button with another receiver and a different chime tone.4.) BUT , it is possible and really the correct way is to spread out the receivers around the house in low volume setting and then you can pair MULTIPLE buttons with the same receivers. For example front door button can be paired with ALL the receivers to play one chime tone and the back door button could be paired with ALL receivers to play a different chime tone.5. None of those options is covered in the instructions.
