## Customer Reviews

### ⭐⭐⭐⭐⭐ Great!
*by T***! on February 27, 2024*

LSF ….. great product :) worth the $

### ⭐⭐⭐⭐⭐ These alarms are loud
*by P***T on February 25, 2023*

There is nothing that I don’t like about these alarms. They are great really loud they come with a pair of ear plugs. Easy to install and only has on and off switch. I have another one that’s is a pain to turn off. Will purchase again.

### ⭐ Find something else!
*by E***S on August 4, 2024*

These alarms are a complete and total waste of good money. At a time when everything is so expensive, please do not even give these alarms your time to look at them or much less buy them. I got them to keep my late stage Alzheimer’s husband in the house. They worked the first day and now not one works. He escaped this morning wreaking havoc inside the house and outside. If these miserable alarms had worked I could have gotten him and no damage done. Buy another product but for your sake and your wallet’s sake. Bypass these items and do it rapidly! If Amazon allowed negative ratings I would give these a minus 100.
