Review on YCOCO Magnetic Organizer Refrigerator Storage by Rich Schobinger

They are amazing. I didn't expect them to be as strong as they are. However, they are solid metal and have a giant magnet on the back. They stick very well. I bought 4 of these (2 sets) and am not disappointed. I was able to make two rows of standard size spice jars at a time! So happy with this purchase! Edit: I have them on my fridge now. Spring. quite a bit of time. They're still holding on. We use them every day. They are still in perfect condition.
