Review: Super item - Very easy to install super sound and sensitivity
Review: Makes me feel safe at night... - I live alone and, in the front bedroom I cannot hear what's going on at the rear of the house. I have attached one to my back door, one to the sliding kitchen door and one to the dining room window. Since doing so I have slept much better knowing I will be woken by intruders. They're loud and the shrill pitch would definitely wake me, and scare off anyone trying to come in. A really cheap and effective alarm. A simple peel and stick. Would recommend.

## Questions & Answers

**Q: Is the led light facing outwards**
A: What you see here faces onto the inside of your window. There are no leds. The outside face has a Doberman security sticker on it. Because the discs are about 3" diameter they are a pretty visible deterent

**Q: How long do the batteries last for?**
A: It depends upon how often the device is switch on, location, and the quality of the batteries installed. My 2 devices are permanently on, the batteries have lasted more than 12 months.

**Q: Are these left switched on continuosly or supposed to be swtched on only when required eg. when going out, please?**
A: There is a switch on the unit. You stick the device on your door and switch on. If the door is vibrated the alarm will sound. If you want to open the door you would have to switch off the device  but the rest of the time it can be left switched on

**Q: can one remove the units without damage? Thinking for the future. Thanks**
A: Not tried to remove one yet. I would imagine a window scaper might work but i wouldnt stick to wood or paint

### ⭐⭐⭐⭐ Good but.....
*by M***D on 12 November 2021*

I was not totally sure what to expect of these but I would agree with some of the other reviewers. These are so simple to install. Simply peel off of the backing and stick on. I did clean my window thoroughly first to make sure they stuck. I like the red warning logo that is the sticky pad - anyone looking from the outside can be left in no doubt what these are. However I fitted one to the glass panel of my front door and tested it. Oddly if you touch the glass panel directly on the outside of where the alarm is mounted it sounds and it is loud...certainly would deter any chancers. But when I opened the door with the door chain on even the motion of the chain abruptly stopping the door the unit did not sound. I needed several attempts to get it work. It seems location is very key here. Sensitivity of the alarm has been mentioned before but I was surprised that touching the glass panel immediately behind the alarm set it off but banging the door open against the door chain did not. I will of course leave it on but I would suggest it is perhaps best for glass panels on conservatories or vulnerable window glass.
