The glass alert alarm is brilliant, sensitive and very loud.I have one on each window and patio door - a great deterrent for any burglar!

I bought these products for the window, not too big just the right size. One thing about them, they are very loud so I'm sure that anyone who tries to break my window will have a shock.

Easily fitted using double sided sticky pad with security warning to opening windows and glass doors and garage window. Easy to switch to off, low sensitivity or high sensitivity. Pack of 10 is sufficient for whole house with a couple to spare for luggage when left in hotel. Recommended as an effective deterrent and good value for money. Mr RW

After experiencing a burglary in April, we were advised by the police about the use of window guards for further protection against burglary. We ordered 10 and later a further 5, all of which we are very pleased with, as they offer a deterrent to would be burglars. Mrs TH

The product itself: Stick on 'Window Guard' alarms. These things go off at the slightest bump; the kitchen window alarm goes off if you accidentally drop something in the sink! Nice and loud too! Have full confidence they will activate if someone attempts to force any windows/doors downstairs; will hopefully deter anybody snooping around. Going to order more in the future for upstairs windows just for the sake of it!

We recently bought a quantity of Window alarms from yourselves, which we are very pleased with. We already had some in use, given to us by the Police. The items you have supplied are of very good quality and are extremely good value. They were delivered the next day, and with the tracking system and email's received we were able to plan our day, as not to waste time staying in. We will definitely use your company again if and when the need arises. BP Worcestershire

When I was sticking these to the windows, i pulled the plastic tab out of the battery compartment before i stuck the first alarm to the window, and the noise gave me such a fright i dropped the alarm onto the floor, and all my children came running to see what the noise was. After sticking them all to the required windows, i gently flicked one window with an alarm on, and the alarm went straight off. This was only on a low setting. LR Shropshire

The glass guard alarm is excellent,and is a very good addition to my house alarm. I installed five units which when tested all activated before the house alarm was set off. The selective sensitivity and very good siren make the units highly effective as an alarm and a deterrent to intruders. JS

I love these little gems. There are almost no panes of glass in my entire house that are without them. And, I've not stopped buying them, yet. The sensitivity is great. I can set one of these in "watch" mode and gently/slowly move the point of a small screwdriver towards the window pane and, even if there's not even a sound made by the driver point as it touches the glass, THAT ALARM HAMMERS THE EARS, every time. Whatever opening is used by a burglar to get in, by a window, they can't afford these little babes to throw their incredible noise back out through that opening - trust me! And, if you have more than one of these on panes of glass in the same window, then what proves to be enough to set one alarm off is perfectly capable of triggering some of the others, too. HELL, FOR BURGLARS! They hate noise, they hate taking too long and they hate attention!

I have been using these types of alarms on my downstairs windows for some years and this is the loudest version I have ever had. Swift delivery too. LMcS London

I have a small antiques shop and I purchased a few of these to put on the more expensive and larger items. There is one on the back of an old painting and one on an irreplacable vase. If anyone was to try and move them it will set off the alarm. Brilliant little device. MH Kensington

Glass Guard Window Alert Alarm Features

Glass Guard Window Alert Alarm Description

The Glass Guard Window Alarm is an effective low cost vibration alarm that can be used for securing windows or patio doors.

The Glass Guard can also be used as a personal property alarm to protect Computers, T'Vs, video's and cabinets etc. Supplied with batteries and strong adhesive tape.

Use the sticker at the back of the unit to stick the unit on glass pane, door or window.

1. Turn the switch at the left side to ‘high’ or ‘low’ to begin operating. A signal will be given out to announce the unit is in good condition. When the glass is hit, knocked or cut by anyone, the siren will sound for about 20 seconds and then reset.
2. The unit can be set to high or low sensitivity. ‘High Sensitive’ mode will detect a little vibration. ‘Low Sensitive’ mode will need a stronger vibration to make the unit react.
3. The unit will also perform well on wooden or metallic windows and doors.
4. If the unit is not placed in the middle of the door or window, use ‘High’ mode.

Operated by 2x1.5v AAA batteries. Always check to avoid low battery .
