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

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.

This alarm is first class. Works instantly anyone touches the door handle! Well done 👏

The item is very sensitive to any movement and sometimes makes noise. Otherwise very useful.

The media could not be loaded. We run a holiday let and health & safety dictates all doors exiting the property must be keyless - so people can get out at any moment. We were concerned about our guests who have dementia or young children who may decide to explore alone. We bought 2 of these for the bedroom area (it's a bungalow) and ask guests if they would like to use them. The sensitivity levels are good - the highest sounded the alarm when my hand was a couple of mm away. The alarm is loud! These are easy to add or remove to door handles, and very simple to switch on and off, and to adjust the sensitivity.I didn't test how well they work if someone trys to pull the handle from outside - I will test that at some point as I guess that's what most people want them for.

Nice product did come with batteries however it doesn't go off when you touch the door handle which my old one did, it's quite loud when it does go off. But it's not as good.

I wanted a product that could alert me instantly if anyone tried breaking into my house, recently there was an incident on my road where a gang of men carrying weapons tried breaking into a house. The door defender hangs on my UPVC door handle. It has various sensitivity levels at which it can set. I have only needed to try the lowest level 1, as soon as I am within about a hands width away from the door defender when it’s armed, it goes off. I don’t even need to touch the door handle for it to go off. The alarm is loud but not as loud as say an outdoor alarm. It has a small red light that shows the device is armed. I suspect my neighbours across the road couldn’t hear it but next door could. I feel more comfortable knowing that if someone did try breaking in at night, I would hear the alarm. I now have these on all my outside doors.

Total waste ofMoney! 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!

Hi Guys, this is such a great product, simple and cost effective but most of all peace of mind. Last one at night places on the door and once you touch it or the door handle it will go off or indeed any time of day if you are worried about escaping The six seconds is ok as no matter what even if your person gets to step outside you are alerted in time.
