Securityman Door Handle Alarm with 130dB Vibration Triggered Portable Door Alarms When Opened - Perfect for Kids, Toddler, Elderly, Hotel, Travel, Bedroom (2 Pack Door Security)

This works extremely well, just as advertised. It sounds a very loud alarm that will scare off any intruder. Very easy to set up and arm.

I use it as portable alarms for inside my truck topper when stopping overnight at motels.Works great - loud.

Works great. Extremely loud. Def recommend.

Sensitive as all get out, loud enough to wake the dead - well almost, and pretty darn inexpensive. What's not to love???

The product works but getting batteries to fit the device can be a struggle until one gets the hang of it. They fit very tightly. Although the directions explain how to adjust the sensitivity level (volume) of the alarm options the loudness sounds the same on the ones sent to me. The delay before sound set button works. However, it is not a simple thing to set the alarm to permanently delay and/or to use a certian volumne if it will do those things and this is something this reviewer hasn't yet mastered and wonders if the device will actually do? It can be hung on a door knob and return to stillness there, but I suspect that every time one tries to remove it within the delay frame and get it turned off so that it doesn't harm one's ears (sound can be too much after awhile at 130 db if I got that right), one will find that doing be hit or miss or that the alarm will nearly always go off . Other than for these things it is one of the better devices in terms of loud enough sound to wake people up inside a house and alert people on the outside as most devices use only 97-110-120 db in the USA that do this door knob thing or are applied to windows and carry key chains and the like. It also has a good sturdy feel and feels good in the hands and the back cover slides off easily enough for battery change.

They do the job but the only thing I don't like is we take them off a couple of the door in the morning that we go in and out of a lot and sometime trying to turn them off they get set off because they are very sensitive. However, if small price to pay when someone is trying to break into your house. Some creep tried breaking in five time and several time they tried coming in the front door they left white power all over the door and ruined our locks. They have also tried removing our back privacy fence gate and I caught someone looking at me in the patio door at 6am in the morning. He was African American or at least I am assuming he was American maybe from another country and he was there to break in, but he ran off. Now someone calling our phone saying what dirty things they like to do to me. Sad, but the police don't care they won't even take a report. They say call us when someone actually in the house. I might be dead at that point. I got indoor cameras because someone took down our outdoor one and smashed them and of course no images of who. So indoor Hawkeye cameras now, door alarms, bear spray and crowbar. I don't even go in the front yard without bear spray it's that crazy. I be taking in the back yard too when I start my garden. Can't leave garage door open when mowing got make sure I lock myself back in the back yard. Next step when I get the money I guess will be gun lessons. We have to save ourselves nobody going to save us. These alarms are loud and sensitive they will go off if you wiggle the door knob with no problem and break in past the dead bolt will be way more than a wiggle.

Easy to use and does a good job

Not sensitive enough
