Submitted on 10/22/2012 Ron L
Had a large steel door that I never protected with my security sytem because the magnetic switches never worked. I just had a heavy duty lock on it and trusted it would work. Now I used this switch and the magnet isnt blocked by the steel door. Fixed a problem I lived with for a long time.
