Door alarm
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.

Great product
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.

Affordable and effective
It’s an effective device that you fit to the door handles. Easy to set up and use. The only issue I’ve had is false alarms due to strong winds moving the device through the keyhole but generally very good. If someone attempts to open the door they’ll get a fright!

BUILD QUALITY?
Took delivery very recently. I read some reviews with regard to the batteries, so decided to immediately change them for Duracell. So far so good. Having done so, I found the screw to secure the battery cover had no fixing. I could hear the nut rattling around in the unit. Presumably caused by either a poor "captive nut" or just poor design. My cover is now "secured" with sellotape! Not impressed. UPDATE: Just. noticed another buyer with the same problem! Decided to bin mine now, the "nut" is moving freely around the unit and I fear it may "short out" when in use. I bought the Sabre version from Amazon, very much better arrangement for changing the battery and same price!

Loud alarm when touching door handle
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.

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!

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