My DH isn't much of a handyman, well not at all actually. He doesn't even have a drill. i am desperate to get the magnetic locks for my kitchen cupboards but I'm worried he won't be able to put them in. Was it difficult and what does it involve? Thanks so much. My little one is driving me insane with his fascination of what is inside all of my cupboards and they way they are designed I can't use the standard ones.
