These alarms are loud
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!
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.

Battery problems?
I love how loud they are but one of mine isn’t even working after only about 1 1/2 months. I hope it’s the only one that malfunctions.Later review:I don’t understand why all of the alarms batteries are dying so quickly! Sometimes in a month! Very disappointed! Would not buy again.

Very poor performance
The sensor keeps beeping unless it is very tight to the alarm. Worthless

They are very LOUD!! And that’s just what we needed.
They do their job and more! The human keeps the door shut and the farm dogs don’t like the noise so they don’t try to get in and the inside puppies stay away from the door and stay inside. Very happy with purchase.
