I’ve never had any problems while we’ve been traveling or camping. There was one time the camper had been in storage during a very hot time and one of the pads came loose. I pressed it back on and haven’t had any problems since then. Since there are 2 on the refrigerator door, I do have a backup in case it happens while I’m driving.
I’m sure that would work just fine. They work great and seem to be strong. My locks came in a 4 pack so I went ahead and used an extra one. It’s cheap insurance. 😀
