4 X WINDOW & DOOR BURGLAR INTRUDER ALARMS WIRELESS SENSOR ** SOLD OVER 1000 + **

Great little product for that extra piece of mind

They are good but not if you're turning them on and off like I need to. Used them on front and back door. Lasted 6 months which may be good as we were getting heavy use out of them. They did fall off a few times once in the middle of the night, which was interesting.

these are a £1 each and can not believed how good they are for what i want . i have a front door a living room door both behind my head if watching tv and could not hear if anybody was behind me NOW i can i put one one me gate which is only 3feet from me front door and means no one comes in my house that i cant hear . i did say for what i need .but £4 for 4 try them you may be suprised cos i was .

For the price they work well clean surface before attaching if using supplied sticky pads they seem to hold firm.Good for use on doors and windows internal only as there not weather sealed good noise when activated would make a theif think twice not tested battery life yet takes small hearing aid batteries.

Great idea and am pleased with them but the stick on design is iffy. After a while they fall off causing us heart attacks in the house as we think an intruder is trying to get in! Had to use a strong glue on the PVC which seems to of made them sturdier

Blinking heck these little blighters are loud for their size. Easy to affix to Patio doors (Double sided Stickly Tape already attached), fly screens, windows or any other internal opening you want to keep monitored. Batteries ARE Included. Great Product for the price & for great piece of mind. I take a couple with me on holiday & affix to the Patio & Entrance Doors of the Hotel / Villa. Also good for keeping an eye on those little ankle biters (Toddlers) to make sure they do not open the External Doors or Gates & make a quick getaway...

They work but have since noticed they are available at Poundland stores for less money

Good value for money and work very well and loudly but have not yet worked out how I can fit themas my windows are not flat edged and as yet have not thought of a way to fit them so that both partsare level and close enough not to set the alarm off.
