Wireless Doorbell, PHYSEN Waterproof Door bell Chime Kit Operating at 1300-ft Range 58 Adjustable Melodies 5 Volume Levels & LED Flash, Doorbell Alarm for Home/Classroom, 2 Push Buttons+4 Receivers

Good product, well packed, good price. My old wireless doorbell died and I bought another brand, one bell with two receivers. But I soon realized that I needed a third receiver. So I bought the same model, just one bell and one receiver. But somehow the third receiver didn't respond to the doorbell. So back they all went.Then I bought this PHYSEN kit: two door bells and three receivers. Everything works fine. And the maker includes two double-sided mounting pads, four screws and plastic sleeves for screw-mounting and even a small screwdriver. Now that is being thoughtful. Easy to install and it all works together. I can't tell which door's bell is ringing, but the second door is a service entrance to my apartment that never had a doorbell before.

Cops came by the house Friday at 5:50 AM because we had to evacuate due to fires. We did not hear the door bells. He came in the back door to wake me. That day I ordered this product and installed them immediately.This product is exactly what it says it is. We are hard of hearing so we purchased this for it's ability to have flashing light and loud sound. It does both excellently.Took the four receivers out of the box set the ring tones as instructed for two door bells paired easily and quickly. I highly recommend this for any family with elderly who are hard of hearing, which in my house is 3 people.

I needed a wireless doorbell with more than one receiver, so I would be able to hear it in different rooms of my house. This had 4 receivers and I am using 3 right now. I liked that it had many doorbell rings to choose from and that there were different volume levels. It was easy to set up and is working well.

The volume was plenty loud for my area.

More than a doorbell, we use these all over the place for use by an individual with limited mobility to be able to get assistance at the push of a button and wonderful tones and melodies! So quick and easy to set up, the hardest part is deciding which of the 50 tunes to use.

works great, got the double for my parents' doors. They are both hard of hearing and these are adjustable tones and volumes and work great. They can tell the difference between front and back door tones, easily.

Got these to alert my elderly parents who live across the street and never hear their phones ring when I call. I keep the button at my house and all three chimes plugged in throughout there house. They work though all the walls from all the way across the street!
