Gosh, I like these things. Just the solid sound of the "click," the feel of the door ... I had no fears that my difficult child would break into my ofc last night, plus, the Christmas presents are in the walk-in closet in my room. The handyman said that if difficult child wants to get in, he can, but he'd have to do damage to the door. I specified that these locks would show damage and he wouldn't be able to sneak, and the handyman said, "Absolutely." We told difficult child he has to pay the portion of the bill used for lock changing, which is $100. (4 hrs, 100/hr. I had lots of other work done around the house!) He was ticked but he had to agree, it was a logical consequence.
