Review on 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 by Peter Alradwan

For an inexpensive product, it works very well. In the future I will install a permanent doorbell system, but this product serves my need for now. I am working remotely from an office in the back of my house. Ordered with 3 ringer units: located 1 in the front of the house, 1 in the kitchen area and 1 in my office. My house is 100 years old with thick plaster walls and there are no issues with the wireless signal. Great when a delivery requires a signature. Before this doorbell, I could not hear them knock. Most delivery folks ring the doorbell to let me know when a delivery made, so I can quickly grab the package from the porch
