What is the sensitivity range on one of these alarms? Does the alarm go off if a window doesn't have one on it but the window next to it does?

I ha one on a pair of patio doors, and it can be triggered by hitting either glass door or even the frame. You can adjust the sensitivity of them to suit the situation, it's just controlled by a small rotary control on the side.

How are these stuck to the glass? If I want to remove them will my glass have glue etc residue which needs cleaning off? Many thanks

I haven’t tried removing them but lighter fluid is good for removing sticky marks . Have also had success with detol spray on tape residue .

Good value for money.

Very good. it is loud and easy to use. I have had the same battery in for a year and still working. I do feel a bit safer. Doesn't go off with every small vibration.

Brilliant safety product.

Great product. You can adjust the sensivity and it is really loud so you can hear from another room or upstairs in the house. Great safety product. It is more expensive but some other products are not loud enough or not adjustable.
