Unpack & fit as required
Purchased for front/ back door alarm protection after attempted kicking/ break in whilst asleep at night.Excellent value, quality, noise level, functionality & easy to install, much smaller than I was expecting, which gives the user a wide variety of fixing areas, plus this product is Police approved!

Had to use both for same location
Wanted to cover 2 doors, but found because my patio doors slide open that putting one alarm on one door would cover that, but would not trigger if the static pane was even thumped - was had to use the other alarm for that instead of elsewhere making ti affectively twice the price.

Random alarms
Loud, slimline, easy to turn on and off. However, both can go off randomly, which is a shock of it happens in your bedroom in the middle of the night!! If this keeps happening, I will contact the seller, as my brother had the same.issue and needed replacements. All in all, good value, a helpful security deterrent and they adhere well to windows.

Brick your window and they might work.
They do not work from outside when you bang on your windows or doors.only work when you tap them from the inside.So not good for you but great for the burglars.Rubbish.

Extra deterrent
They easily stick onto glass windows and doors. They have a loud siren but we’ve only tested them, thankfully not had them put to use. They are just another deterrent which create a lot of noise but were recommended by our local neighbour hood watch team.
