Philips Wireless Doorbell Kit, Battery-Operated Reciever, LED Alert Lights, 1 Push Button, 32 Melodies, 3 Volume Levels, 150 Ft Range, White, DES3140W/27

Quick and easy installation along with dual tones make this an excellent choice. The price made it very affordable.

Needed a door bell that will not require wire, this was perfect. Easy to setup. Comes with required battery for the remote.

Easy to set up and works well. Loud enough to be heard on the 3rd floor of our 3-level house.

This is the type of simple 2 ring tone doorbell with an adjustment volume button just under the doorbell unit. I set it to the traditional 'ding dong' tone and can put it where ever I want. I have been looking for a narrow enough push button to put on my narrow door frame of 1 inch, and this is by far the narrowest I can find. One thing I have to comment is that the product advertised mentioned the size of the doorbell but NOT the pushbutton so I had to take the chance. Since it mentions the push button uses a CR2032 button battery so I estimated that the pushbutton should be just a little bit wider than than it.

Very straightforward and easy to use device.
