I bought this to keep my little one from getting his fingers caught in our Lazy Susan. It installed easily and worked well. Too bad it is plastic...and cheap plastic at that. The first one broke after 3 weeks. The second one broke after two! Before it snapped it really did work well though! I'm on the lookout for something better. If I don't find anything good, I will have to clear out the entire cabinet and then install yet another one of these locks. If the mechanism doesn't get used regularly it won't break. Hate to lose the cabinet space, but at least I won't have to worry about pinched fingers.
