## Customer Reviews

### ⭐⭐⭐⭐⭐ A very good, basic door chime to monitor door entries or exits.
*by J***S on May 26, 2018*

I purchase this unit as a entry door chime for my wife's retail shop. I installed it inside on a door entrance overhang and have it pointed down toward the entry door. I followed the enclosed instructions and set the unit for a single chime. You can also set for a double chime ("ding-dong"), and you can change the chime volume. I'd recommend putting a piece of electrical tape over the electronic sensor after you install the battery and while you are handling and installing the unit because it will chime constantly otherwise. Then you can take off the tape and start your tests and adjustments to the unit. Overall, a great way to monitor business or home doors for entry and exit.

### ⭐⭐⭐⭐⭐ Great product
*by H***H on August 9, 2019*

This does exactly what it says it does. Plays a chime when motion is detected. We have it mounted on the ceiling above the area of concern. It was easy to install, only requires a 9V battery. We were able to easily adjust the volume. While we did not readily see where the chime adjustment was, we were quickly installing it. We are going to go back over the unit instructions to see if we can adjust the chime from ding-dong to just ding.

### ⭐⭐⭐⭐ Good for one room store.
*by C***N on June 20, 2019*

I had one for 7 years. The old one had a relay system with had a door bell at the entrance and a relay in the back room. It was great when working in the back. This one doesn't have that. So I have to keep checking the front of the store.
