I get these lock because I do not want my son pull all the stuff out of the kitchen cabinet all the time . but they would not work with the way we cabinet be build and when I put they in drawer , they be pretty easy to pull off with just the adhesive . and two break when unsuspecting relative give they a tug think something be stick in the drawer\/cabinet . I be impress by the mechanic of how they work , but in the end it be just easier to put the non-child-friendly item out of reach . however , if you have a drill and the time to put they with screw - and you cabinet have the right size lip inside and the drawer be snug , it might really be what you be look for . my advice - get a couple and see if they work before buy into the whole system , which be what I do .
