## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great, needs batteries to operate.
*by S***R on April 11, 2024*

We get deliveries, so I put this motion sensor near the door to alert me when we have a delivery. Works great. It even discourages burglars because it makes noise when you approach the front door.The thing I like (and dislike) is that the sensor needs batteries to operate. I like that because I don't need to run an electric cord. I don't like that because periodically you have to change the batteries when it stops working. Overall it was the right choice.

### ⭐⭐⭐⭐⭐ Works Great!
*by R***C on October 12, 2018*

I mounted this near the front door of my barber shop. There is an outlet nearby so I'm using the plug instead of batteries. It works very well. The receiver is in a separate room about 25 ft away from the motion detector. The volume can be set to three different levels. The middle one works great for me. It's all wireless and very simple to use and install. The receiver lights up bright blue and plays a tone of your choice, from a simple doorbell sound to a variety of different songs, which you select by simply pressing a button until it comes to the one that you want. I use it when I'm sitting in my break room and turn it off when I go back to the work area. I definitely would recommend this product.

### ⭐⭐⭐⭐ El Cheapo, but I am having good luck with it.
*by S***H on January 10, 2024*

Range, sensor to receiver, can be surprisingly long (a very good thing) when line of sight between the two is unobstructed . . . . In my case, having the sensor (mounted at the mailbox, 135 feet from the front door) ping the receiver and trigger a chime, successfully, on about ninety percent of vehicle or pedestrian "passes," has proven to be very useful. Because of the luck I've had with the unit, I actually ordered a second set . . . which leads me to an odd anecdote about THAT one! The receiver on the second set has a funny little trick, whereby it occasionally re-sets its chime tone, from whichever I have set it to (most of them are irritating, Chinese-sounding nursery tunes), to its factory default. Weird. I end up re-resetting it about once a month.
