Door Handle Alarm Door and Window Alarm with 120 DB Touching Vibration Triggered Alarm for Travel Hotel Apartment Home Security

I used this on a door to ensure that no one could get in or out without me knowing

This is my 2nd try, first one didn't work neither did 2nd. Motion detection does nothing even with sensitivity at H/L/0. See video, dinged after 30 seconds and extreme motion prior, only worked on rehang. After video I tried banging on door, still nothing Complete waste! Now I have to travel 25 minutes to return to UPS store. DO NOT WaStE your $.

I'm surprised I got an email to review this item. I returned it right away. It didn't work, at all, like described. I may try another one, thinking it could have been a dud...after reading other reviews.

It goes off as soon as you touch it or if there’s movement. We got this for my mother-in-law with dementia I was trying to leave the house. Thinking she live down the road. I highly recommend it

I ordered 2 of these,one arrived in what appeared to be used condition and didn't work.The other one worked as I had hoped,was very loud when set off.Very easy to use just hang it on the doorknob and turn it on.
