Title: Not very secure.
Review: When we moved into the house we live in, one of these were attached to the back door, by a previous owner. I was tempted to cut it off as we didnot know the combination. One day I decided to see if I could get it off in a nondestructive manor. My first attempt was by disassembling the door knob. This only got it off the door. I fiddled with it for about an hour until I couldn't believe my eyes! It opened! Using nothing but simple everyday household items, I was able to discover the combination. After doing it a few times, I could do it in less than two minutes.If I can do it, I'm fairly certain anybody could do it. Beware that these things are not very secure. I laughed when I read about the lengths that others went through to "crack" theirs open.For those curious, the combination was 5408. Currently it is 0000 sitting in our living room as a conversation peice.
