Door Handle Alarm- Door Alarms for Home Security with 120DB Audible Alarm up to 500FT - Vibration Triggered Security Alarm for Travel, Hotel, Apartment, and Home Security

This little gadget is great. I will say its very sensitive. We hung it on a metal door handle & screamed with every little vibration which would of course wake anyone up at night its very loud. I found out if I hang it on a plastic knob it will not go off unless the door is jiggled. Perfect. I would highly recommend it as very loud & that is what you want if someone tries to open your door at night or any other time its turned on.

It's a good concept of a product. Very audible. But, like other people wrote, it keeps going off for no reason. I remembered what someone wrote about using a plastic doorknob to solve their problem so I put a little plastic wrap on the doorknob and now it works perfectly.

Love the product

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.

I have a nosey landlord who likes to enter in my place when I leave for work, so I got one of these to put on the front that would enter in. To scare her so she won't keep coming in while I am not home. At first I didn't think it worked. Oh but it does. It's very loud and extremely sensitive to the littlest vibration on the door. It doesn't have to be the door knob. I love it so much I showed a friend and she wants one

I bought this door alarm and had trouble with it right out of the box. I followed the very simple instructions (only briefly confused by the poor translation from Chinese to English) and had problems immediately. Unit went off at the wrong time, the alarm sound was also defective and it wouldn’t reset at the end of the alarm period. It it useless. The return period has passed so I have to eat the $10 purchase price. Please save yourself the trouble and don’t waste your time with this junk.

I was very pleased at first, but after about a couple of weeks or so, it started to malfunction. It would just go off randomly, with some kind of buzzing noise. Ended up throwing it away.

These are amazing. Very loud. They reset themselves if you don’t turn them off yourself. My friend came over and they went off and she left because she was worried the police were coming. They are very sensitive to any movement. I am ordering more❤️❤️❤️

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

top quality

Works well, and a very loud alarm.

Ideal for traveling to give a little added protection in hotels and is lightweight, easy to pack and put in place.
