Door Sensor Alarm, Remote Control 300ft 120dB Wireless Door Contact Sensor Anti-Theft Door Alarms for Kids Safety, Home Security (2 Alarm Door Sensors & 1 Remote Control)

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.

Great value, but too loud! It also takes a second to hit the cancel button because the noise is so deafening that it was a shock to my system! I panicked. Not sure I was ready for that loud of an alarm.

This is just what I need! We live on a very busy street. It’s very dangerous for our little toddler to get out. There are many cars and people out there. We need something which can alert us when the door is open. This door alarm really does its job!It has turn on/off button, I just turn if off when no alert needed. Besides, it comes with a remote control which has arm, disarm, doorbell chime and SOS options. You can simply disarm it when you don’t want to be bothered by the alarm.The alarm sound is really loud, I can hear it anywhere in my house. The chime just dings twice and then you can leave the door open. The alarm setting will keep on for 1 minute and you can stop it by pressing the disarm button on the remote control, very convenient.Moreover, the installation is very easy, just stick it with the double side tapes. I put one on my front door and another on the window. As he is growing and one day he might try to open the window and sneak out.

My aunt and I have recently gone through a terrifying event where a man has attempted to break his way into our apartment via the front door. It was terrifying! We couldn't catch a wink, even hours after the event. And This man a (squatter) is currently staying directly across from us. We've been paranoid to say the least. When I found this security alarm I had hope it would alleviate some of the fear. Installed it just today and tested it out and I feel SO MUCH Better! It's super loud, easy to install and it makes me feel so much safer that I can activate the alarm via remote if he tries it again. SO worth the price. :) only slight issue is the remote takes a couple clicks to connect to host.

Typical instructions written with language barrier. The setting of modes of alarm i.e. doorbell or alarm or alarm only when open are not in the instructions. Same for total reset...where you get 10 beeps to verify. That requires you to hold the set button while you turn switch on. IF you are using on pool cage door and have right and left opening doors, one install will be upside down...the reason is the magnetic switch is on one side of the 'host'. In support of the alarm(s), they are quite loud. And, arming them via remote from inside is great.

I installed one from the 2-pack I purchased in August and it worked fine. I never used the remote, but just wanted something for when the back door opened. It's not an alarm, it's simply a beep - but that worked for what I needed. Now it's April and both are duds. I put new batteries in the first one, it won't work. Then I put the second one up with new batteries, won't work.
