Review: Sensitive the way you want it to be. - I was adjusting a drape in front of the door-window balcony this is set up at. It triggered the alarm. LOL but I am extremely pleased! The lightest fumbling or criminal activity will definitely trigger this. Also it is nice to know these are good for hindering the openings into your home. This is used at a slide-across balcony door, but it was intended for a smaller window. It is too long at its smallest adjustment for a standard normal slide-across window in Canada.
Review: Loud and Great Security Bar - Sensitive but in a safe and great way! I can hear the alarm from rooms away in case of anything happening, and it does a great job of forcing the door closed and preventing it from opening if someone were to try to force it open. It's sturdy, strong, easy to put together and adjust, and I'll be using it for a long time to come.
