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)

Me gustó, cumple con todo lo que dice el proveedor

Works well, very loud, should be put on most sensitive setting for triggering.

We needed something to put on the doors or our AirBNB when we travel as we have an autistic child that likes to elope and we needed something to alert us if he tries to do so in the middle of the night. These things are super loud. And while, yes they are super sensitive and you're not going to open the door they're on or remove them without them going off, you can successfully turn them off without setting them off. You just have to make sure the first thing you touch is the off switch. My wife normally covers it with a towel when she goes to turn it off so it doesn't hurt anyone's ears. Just make sure that when you set it, that it doesn't start bouncing around when you let go after turning it on, you only have a second or two before it's armed.

Purchase for travel/hotel room security. It is loud and will definitely deter a break-in attempt or alert you if someone is attempting to access your room while you're sleeping. Problem is I also set it off while trying to disarm because it is sensitive.

The volume really didn't adjust to a lower sound, but I thought thats ok because it's very loud and would scare the crap out of someone not expecting it
