Goerpn 2 Pack Ultra Slim Vibration Alarm 130dB Window Alarm for Security, Shed, Door, Glass Break Alert, Home, Office, Dorm Room, RV

They are pretty good quality considering the price. They are very slimline and smart. They are very easy to set up and use and also loud.

Really affective and super loud

We got them to put on our street-facing windows after an attempted break in. They're not too sensitive, i.e. slamming the front door doesn't trigger them. They're very loud when they go off, so will definitely scare off anyone not expecting them. They've gone off a couple of times when things have knocked against the windows, so that's a good sign. Hopefully i'll never need to find out whether they're triggered by someone trying to smash a window again.

Excellent small alarm system which shoulld act as a good deterrent as a first alarm if window broken. Loud decibel siren Red light lets you know its switched on (would be better with two ie. on the glass side to let a perpetrator know the window is alarmed. Overall great price and good quality. Now fitted to all my windows

These vibrator alarms are good. BUT it takes quite a bir vibration to set them off. I fitted one to my back door, I then thumped the door with my fist quite hard, but the alarm did not activate. If you tap the case of the alarm with a coin or something solid it will activate.

Does the jib

I wasnt to sure if these would be any good but their excellent and I would recommend. There nice and loud.

easy to fit and are loud

It’s loud enough once it goes off, but the sensor isn’t very sensitive. You need to shake or hit the window quite hard before it activates. Okay for basic use, but not ideal if you want something that reacts easily.

Ordered 4. 2 were faulty and 1 too sensitive so $45 for one working alarm. No point returning as it would cost more in postage from Australia. Won’t buy again
