When we first got these, they were awesome, but unfortunately, half of ours have not stood up to the test of time. They have not been subjected to any major pulling or stress, but the part inside the cabinet has shifted slightly and now half of our locks (4 out of 8) do not lock at all. And if they do happen to lock about 1% of the time, it is when I need to get in the cabinet, but not when my 1 year old is pulling on the door. I have had to rearrange my cabinets to allow him to get in and play with the plasticware or empty cabinet space and remove everything I was trying to protect from him. In a rental home where we cannot drill holes I thought these were the perfect answer to our child-proofing needs. Sadly, I was mistaken.
