MIKEDE Strong Neodymium Bar Magnets, 16 Pack Black Heavy Duty Magnets with Double-Sided Adhesive, Rare Earth Metal Rectangular Magnetic Bar Magnet for Kitchen, DIY, Tool Storage - 60 x 10 x 3 mm

Very powerful magnets. Be careful, can pinch hard! Can destroy phones and other devices, so be careful.I tried playing with them and got pinched so hard so many times I gave up playing with them. They can break your fingernails trying to pry them off flat surfaces. If you plan to let them stick to something make sure you put a way to get the back off again. Once they clamp on they are on!

Small but super strong magnet. I tried multiple magnet sheet out there, but neither could hold any very light thing, while this one can hold everything perfectly! And the tiny size make it possible to be attached to any surfaces. Highly recommend

To be fair, I had no idea how strong "N52" is as a rating. I just needed the magnets to hold through a series of fabric pieces as well as support weight. The magnets didn't come with any details to the packaging. And they are EXTREAMLY strong. Word of advice, to remove these magnets, slide them off one another, do not twist. I repeat, do not twist. I was holding these against my chest trying to twist them off (hard to grip and separate), and ended up pinching the skin on my chest as they snapped back in place. Additionally, while taking my display down today, I unfortunately discovered that the magnets will SHATTER if they collide. And they will collide, the force is strong with these. But they got the job done, and left a weird hickey looking mark on my breast.

Super strong. Worked perfectly for my application except I had to use industrial glue to attach them to the wood surface, and the foam tape was too weak to hold them on.

They're very strong, just like everyone says. I bought them to hold a small calendar on my fridge, and they're perfect for that. The calendar flips through the months with a metal coil hinge/binder, and through the coil is a thin metal rod with a dent/curve at the center, so that you can hook the curve over a nail to hang the calendar. Well, my first idea was to just hold the calendar in place near the top of the calendar though the paper, but since these magnets are so strong, of course it was attracted to the metal coil and rod. So, as it turned out, all I had to do was just put the magnet strait on the fridge, and then magically put the calendar's thin rod thing directly on the magnet --and it held. Now, to flip to a new month with my calendar, all I have to do is pull off the calendar, flip to the next month, and return the calendar to the magnet --so easy!!! In the past I had to remove four weaker magnets I had holding the calendar. These magnets are so much better!!! I have the rest (five remaining) stacked together, also on my fridge, and they hold a pair of curved embroidery scissors which I keep handy on the fridge, for removing loose threads and cutting off labels of cloth items deep into the seam. Stacking the magnets five deep like that works well to keep the curved pointed tip of the scissors from digging into and scratching the fridge when I remove the scissors from the magnet.So, that wiped out my entire pack of six magnets for those two purposes, but these are such great magnets that I'm contemplating buying more for other uses. I also like how they look so much nicer on my fridge than the big black magnets I used to have, since these ones are smaller and prettier with their shininess. On the fridge, they have a minimal aesthetic, and match well with my other stainless steel "pushpin" magnets. I highly recommend these workhorses which every household needs!!!

The magnets are strong but brittle. One fell on my wooden floor and broke into three pieces.Also the stickems that come with them, are useless. Too weak to keep the magnets from pulling away from the door andmagnetising together. I know no such word don't know how else to describe it. I ended up using Gorilla glue to stick them to each side of the door.

Really powerful magnets. I have metal cabinets in my garage and these are great for holding all kinds of stuff on the cabinet doors and cabinet walls, inside and out. A single bar can hold a pair of gloves. Another one on the cabinet door to hold a diagram while I work. One on the bottom of the overhead cabinet to hold a razor knife. One to hold a mechanical pencil. This is the second set I purchased. Just don't pinch you finger between two of them. Can be a bit of a pain pulling one off sometimes, even using plyers.

These are insanely strong magnets. They will even pull at each other from inches away. They did suit my purpose to have a foam board sign that's easy to hang and remove from a wire grid shelf for my booth. I only gave it 4 stars because they do have the ability to break which I've never seen a magnet do. I think it was when one piece attracted another and they slammed together pretty hard. Because I can't just snap it with my hands. You can see in my photo. Otherwise they're very good.
