Review on Refrigerator Magnetic Spice Rack - 2 Pack Magnetic Shelf Organizer for Kitchen, Cabinet, and Stove Storage - Space Container for Small Kitchen/Apartment - Drill-Free Installation (Black, 2 Pack) by Vivek Allen

I love these spice racks! The magnets are very strong - make sure you position them exactly where you want them before you start stacking your spice jars. I've moved mine a few times and each time I had to take out all of the spice jars before tearing down the shelves. refrigerator with both hands down. (In my experience, magnetic shelves filled with spice jars shouldn't be moved unless you want them all to fall to the floor.) They're cleverly designed to keep small spice jars from sliding off the shelf. (The "safety bar" is at the right height ONLY so my little jars don't pop out while I'm rummaging around for what I need.) I'm so happy with these shelves - I was originally looking for a spice wall mount, but then I am stumbled across these and they are much more convenient - and no harm to the apartment!
