Strong Neodymium Bar Magnets with Double-Sided Adhesive, Rare-Earth Metal Neodymium Magnet - 60 x 10 x 3 mm, Pack of 6

In the event you were not aware of it, this kind of magnet--Neodymium--is among the VERY STRONGEST available today (Genuine INDUSTRIAL STRENGTH--which I discovered about twenty years ago)!!! I needed to fix a little household problem: My fridge, over maybe a year, has had a way of staying open a small crack, even when there was nothing holding it open. I thought one or two of these guys might be the solution to my problem. As it happens, they were the PERFECT solution!! I carefully fastened two of them to the refrigerator door, under the rubber seal, using the handy adhesive strips included in the package. Now the door closes in a much more SOLID fashion...EVERY TIME. A tip: Please make sure these get NOWHERE near anything like a tape cassette...or they will be "history!!!" Another tip: As strong as they are, it can be a bit difficult pulling the separate magnets apart, at first. It takes some practice to "get the hang of it!!" ; )And, the price was reasonable for a SUPERIOR product.

Works well for my need. I wrapped them with washi tape (and created a tab for lifting them) in pairs of 2, creating 3 magnet bars that I use with my diamond painting canvas. I use a light pad attached to an art easle and the incline causes the canvas to slide when using the mediocre magnets that came with the light pad. These solved the problem because they are strong enough to hold the canvas in place. I did have to wrap them with washi tape to make a tab for lifting, but I knew I would need to do that when I ordered them. These are vert strong magnets so care must be taken that they don't snap to each other quickly or they might break. Care also needs to be taken that you do not let them snap together in your hand because they can and WILL pinch and cause a painful blood-blister. I would buy these again.

I took the magnets out of the box, began to remove the first one, and two of them literally cracked in half. No excessive force used. Certainly, not worth the price. I can only imagine if this happened in a family with children or dogs and a piece of magnet was picked up by a small child or dog. If I could give this product a "0" for durability I would.

My primary use for these was to attach my iPad to the fridge for kitchen entertainment. I have a rugged case and I've affixed 2 of the magnets to the thick rubber grip areas of the case.While they "stick" to the metal surface very well, the iPad itself is probably a little heavy to keep the magnets from sliding down the metal surface they are attached to. Originally, I had the magnets on the smooth surface of the case which is basically against the back of the iPad. Because the iPad kept sliding, the magnets lost their grip on the case (foam tape detached itself) causing the magnets to slide together against one another. This caused the iPad to slip and fall to the floor (unharmed). The double sided foam held up 3-4 days perhaps.I then used 3M double sided tape to reattach magnets, but they are attached to the rubber grip area of the case. The iPad still slides, but I have placed a "stop" on the fridge underneath the iPad to keep it from sliding. This has been working great for me for a couple weeks now.I'm also using the magnets to store a magnetic measuring spoon set. Again using 3M double sided tape. This is working very well also.

The adhesive strips come separate so you don't have to use them (I didn't so I cannot comment on the adhesion). These things are incredibly strong for their size...strong enough to be hard to get the magnet off something once it is flat on it, and to separate them from each other. They come pre-separated by same-sized pieces of plastic but are still very hard to get apart.I bought them to hang a sidelight curtain on the metal door frame so I did not have to drill. That curtain isn't going anywhere!
