Good item

Excellent item

I love these items.

This item is sensitive,it was on a window next to the door and when we shut the door very hard it goes off
-
It's not as loud as other similar items, but loud enough for me.
-
great item but battery cost is not good
-
These would be good to use to protect display items in a store -- paintings and such... anything in which movement is likely to cause vibration would set it off
-
Good item.
