M520+F55 Wireless doorbell

Fantastic product. It only took me about three minutes to install these doorbells. Each doorbell has a different chime so it's easy to distinguish which door a person is at. They're small, so they don't distract from the exterior of the door or the house. I live in a rental house and I didn't want to take a chance of ruining the exterior paint on the doors or on the house, so I attached the doorbells to the exterior glass on my two storm doors using some clear double sided tape. They've been in place for several months and the doorbells are still firmly attached.and working perfectly.

This wireless doorbell is very easy to install and is immediately effective. I installed one button on the gate leading to the back door, and the other one 30 feet away on the corner of the house by the front steps. The receiver is in the kitchen and is loud enough to be heard 60 feet away. Now we will never miss a visitor or a delivery while someone is home. Also our friends are happy to be able to ring a doorbell instead of having to call our phones to let us know they want to see us.

Nice doorbell. Not too difficult to set up despite the fact that the instructions completely suck. E.g. it says it has to be plugged into an outlet at least 3.3' high but it works fine in my outlet that is the normal 1' high. The sound and volume instructions make no sense whatsoever. I had to figure it out myself and it magically worked. It has lots of tones - some whole songs - I picked one I liked (not using the instructions). In the end I like it and it works.

Well, it is a simple device doing a simple service, and it works great, quite simply put. The activator and the ringer, in our application, are about 125 feet apart. The button is out at the locked entrance gate to our property, and so far every time someone has pulled up to the gate and pushed it, the ringer inside the house has rung. Wow, what a concept and there are no wires. Truly amazing. The next test is battery life. I wonder if a tiny little solar panel, about the size of a half dollar would make this unit completely self sustaining. Something to ponder... probably already been done.

Good sound,easy install

Easy to install, works well in all weather, SO MANY sound choices, easy to adjust volume, looks cute!

What a brilliant door bell!! We love this thing!! It has over 30 ring tones to choose from, including holiday tones! It has an adjustable volume control, great wireless range, functions as described!

Works right out of the box, easy to plug in and stick the bell on the exterior. Loud and clear for aging parents
