## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great!Loud enough!These door alarms are really useful!
*by A***S on July 29, 2019*

I am a housewife.My mother recently diagnosed with Alzheimer's disease.So I took her to live in my home.Just recently,something happened that I almost regret a lifetime thing.I was cooking at the time,I do not know my mother ran out,fortunately,after she went out for five minutes,I found out that the door was opened and she was gone.(If I realize it a bit later, I don't know what will happen.)Then I started to go out and find her,fortunately,someone saw her and she didn't go too far.So I found her(Thank God).When I took her home,I immediately called my sister and said this thing.She suggested that we take her to a nursing home,but I didn't agree,I want to accompany her.So my sister suggested that I buy a door alarm(Her friend has bought,and said that it is useful).So i bought these door alarms.It is easy to install,easy to operate,and the alert is very loud.And there are 4 alarm modes. As long as someone opens the door, it will alarm.Even if I am cooking,I can hear the alarm.This door alarm is really useful, my mother went out again a few days ago, but this time when the door opened, I heard the alarm,so nothing happened.I really recommend that there are old people or children at home,you can buy these door alarms.

### ⭐⭐⭐⭐⭐ Loud with good selection of sound options
*by J***Y on May 18, 2021*

Good and loud. Easy to install batteries. Default alarm, option 1, will continue to sound even if door is closed after opening it, or choose the option that stops if the door is closed immediately afterwards. I like the option to sound and keep sounding after the door is closed so that burglar will not know what to do even if he closes the door. If you set it off accidentally, reach up and turn it off with the switch on the side. The option 3, will shut off the alarm, when the door is closed. If the on/off switch is used to silence the alarm, it will revert to alarm option 1. If the set button on the opposite side is used to silence alarm, it will keep its setting 1,2,3 or 4. I like Option 1, so I just use the on/off switch - on to arm and off to disarm. It's a great back up in case my regular house alarm is not working.

### ⭐⭐⭐⭐ Stopped working after 2 weeks
*by D***W on January 9, 2022*

These they are very nice good quality, made well and good design, but after two weeks both of them just completely stopped working. Perhaps I got just a bad set it does happen. The seller made it right and offered me a full refund with tax. They wanted me to be happy and were very easy to work with. I appreciate their communication.
