Defender Door Handle Alarm - Wireless Hanging Intruder Alarm for Metal Door Handles - 125dB Siren Movement Detector - Door Knob Touch Sensor

Great value for the money, very easy to use great volume of alarm. Fits any door with a handle. Very sturdy. Great peice of mind when in alone and at night.

Bought this after a spate of burglaries in my area. It is so simple, but very effective, and very cheap. It gives off a very loud shriek when the handle is moved, which would put anyone off. Very happy with this product, and I feel much safer with it.

Needed for son to alert when sleep walking, and its great for this. Its very sensitive. On the highest sensitivity setting, you only need to touch the door handle gently with one finger and the alarm goes off. Literally no idea how it works - very cleaver. It does have its limitations though. There is no remote control to turn it on/off. You need to manually turn it off, which it self triggers the alarm. Also the alarm doesn't sound for long once touched (a matter of seconds)....its not like a burglar alarm that will continue to sound until someone attends to it. And there is no way of alerting you to it going off (eg to your phone), if you are away from it. So absolutely great to stop sleep walking, or to stop young kids getting out etc, not so much as a burglar alarm.

This is a great deterrent, literally pull plastic battery tab out, set the loudness level and hang it on the door. My neighbour said she could hear it fine outside. Its very sensitive, it went off when she pressed the doorbell without touching handle, and I set it off by being close but not touching it too. I live alone and door fronts a footpath and occasionally someone tries the handle, hopefully this will deter them and the kiddies running on my ramp. I think you need a metal door handle though, but Id try popping a metal chain on the handle behind it, reckon that may work. Im very pleased with it, and neighbour likes it too, and is pointing one of her cameras to cover my door for me, so Im feeling much safer and will sleep[ better.

Well, these door alarms work wonderfully and are easy to use BUT one of the two I ordered has broken when I simply went to put it on the door handle. I don’t think I’ve had it out of the box for more than 3 minutes. If you get a “good one” you’re grand, but clearly there are some faulty ones so it looks like I’m stumping up £500 for a faultless system after all. You can’t have a security solution that “might” work. Not reliable - a shame! The other one seems great. Oh well!

Safety and security. Like the alarm system. Very loud.

Total waste of Money! As a victim of rape in a new property living alone as a female I can honesty say this product had me petrified! It woke me up at 3am on first night in the house through ear plugs so it’s loud! But I was laid awake then in the pitch black petrified thinking someone was in the house for half an hour before I dare move. I was the definition of petrified ans routed to the spot my heart beating so loud I could hardly think. It then went off AGAIN! Before I moved. I must point out it obviously turns itself off as it woke me up then turned off then started again half hour later! NO ONE WAS THERE! So I was crying petrified for NO REASON! Total waste of money as how can you use something that is going to go off randomly in the middle of the night! I see others have had the same issue! This product should not be allowed to be sold as I basically paid the money for something I can’t use that nearly gave me a heart attack in the process! Money I should of just kept!

Simple easy and works straight out of box

Eigentlich ein super Produkt! - laut, einfach anzubringen, - funktioniert hervorragend! - Eigentlich.... - da es in meinen Augen ein großes Manko gibt!- er lässt sich nicht ausschalten ohne Alarm auszulösen! Der Alarm wird angebracht, schaltet man ihn ein, so hat man 6 Sekunden Zeit um sich auf mehrere centimeter zu entfernen. Danach ist der Alarm aktiv. Nähert man sich nun dem Alarm auf wenige Zentimeter (jemand versucht die Türklinke auch nur anzufassen(auch von außen) ) geht der Alarm los! - eigentlich super.. aber abschalten geht eben auch nur indem man ihn anfasst und somit löst man immer dabei Alarm aus!

Diese Alarm tuer griff ist leider nicht ok Knopf lässt sich nicht verstellen und spring viel zu spät an werde ich zurück schicken

Der Türalarm geht bereits los, wenn man ihn einschaltet! So sollte das nicht sein.
