My original review: This doorbell makes a nice loud sound. I have the receiver (bell sound) plugged into an outlet in the center of my house, and I can hear it all over the house. My only complaint is the fact that the thing that gets pressed doesn't have anything to tell your guest that it is a doorbell (It should have something that states "doorbell"). So when I mounted it on my outdoor wall, I did put up a small sign that said doorbell. This was very affordable, so I do highly recommend if you can't always hear someone knocking on your door.
***UPDATED REVIEW 6/16/15: I've changed my opinion on this doorbell because after one year of use, the receiver has died. Also, the button tends to stick when pressed and you have to press the top to get it unstuck. So, into the trash it goes.
I plugged in the bell part downstairs and placed the button upstairs on her night stand next to her bed. I explained how it worked to her.
If you notice in the picture the front of the bell part has a blue colored spot. This is a light that stays on and when the button is pushed the light flashes and the chime/tone plays.
It works exactly as I thought it would and my wife is very happy not to have to yell to get my attention.
There are many different kinds of music/bells/greetings. Some in English some in ???
I would buy this again and would recommend it to my friends.
I bought this item 1 year ago, but it only lasted for 6 months. Initially, I would have to unplug the inside chime from the wall to 'reset' it every couple of weeks. Then it would work for a while until it wouldn't. I wouldn't know until someone stopped by and was forced to knock. Finally after 6 months, it died. I replaced the battery in the transmitter with no success.
I did like the unit when it worked. Chimes are crisp and loud, and volume control works well. Maybe I bought a dud, but I'm hesitant to buy another.
