These shelves are sturdy. The price is good. The shelves have pretty good dimensions-- I could use some shorter ones, maybe six inches long! Mostly, the shelves hold to the fridge, which is stainless steel covered, pretty well. I knocked into a shelf in passing with my shoulder, positioning to go through the doorway beyond the fridge with stuff in my hands. I didn't touch the shelf hard, but it was enough to break the shelf's grip and send the spice jars tumbling to the floor. So these little shelves are best positioned away from clumsy people like me. Mind you, they don't pull straight away from the fridge at all easily. The lateral shove was the problem.

I was worried it wouldn't hold on strong enough to store things I Needed, but it held to my fridge really well and tight fit no problem. Fits all my meds and vitamins just as I hoped!

I was unsure about the strength of the magnet. I was highly shocked. I would definitely recommend this to anyone looking to store many spice jars. Its worth the purchase.

These helped to organize my kitchen as I have limited counter space. I really like them and I am so glad I purchased them. Worth the price.

Super Duper strong magnet. They stick and they stay put! I bought these for my classroom to hold a couple of books on my whiteboard. I also have one holding flashcards on my chalkboard. I took one of them home to have on the side of my refrigerator for a variety of things. I highly recommend these magnetic shelves.

This product holds a lot of weight. I dared to put a wine bottle on it and it worked (not that I would do this in practice). I ended up ordering two more sets since I like them so much.

Since I like this product so much, I'm not going to deduct stars for this. But some of the imagines are very deceptive. The width of two of the shelves is indeed around 11.5", but two of the others in the set of four are around 10.5" wide. Also I don't know where they found that fridge in the pictures but it makes these look like they are 2' wide when they are less than 1' wide. They are honest with the dimensions so pay attention to that in the description and that only applies to bigger shelf (one of the pictures you can barely tell they are different lengths).
