Review on 🚪 Enhanced Securityman Door Handle Alarm (2 Pack): 130dB Vibration Triggered Portable Door Alarm – Ideal for Kids, Elderly, Hotel, Bedroom, Apartment by Monty Barganier

The product works but putting batteries in the device can be a problem until you get the hang of it. They sit very tight. Although the instructions explain how to adjust the sensitivity level (volume) of the alarm settings, the volume sounds the same on the ones sent to me. The delay before the sound adjustment button is activated. However, it's not easy to set an alarm to have a constant delay and/or use a specific volume when doing these things, which this reviewer hasn't mastered and is wondering if the device will actually do it? It can be hung on the doorknob and silenced again there, but I suspect they always try to remove it within the delay frame and turn it off so it doesn't hurt the ears (the audio can be too loud after a while at level 130 db if I understand correctly) you will find that this happens randomly or almost always the alarm goes off. Those things aside, this is one of the best devices in terms of sound loud enough to wake people up inside the house and alert people outside as most devices in the US only use the 97-110-120 dB, that this doorknob generates. Attach things or windows and carry key chains and the like. It also feels good and feels good in hand, and the back cover is easy enough to remove to swap out the battery.
