Review on Powerful Neodymium Bar Magnets With Double-Sided Adhesive - Ideal For Home, Office & Scientific Uses - Pack Of 16 Magnets by David Foster

So strong you have to slide them apart. Also you get a lot if them for an affordable price. I thought I would try these for a couple of uses. One on the refrigirator we like to hang a few family & pet pitctures. Using these the photos no longer fall off when we close the door, nor do they slowly slide down. Awesome! That was an issue we didn't even think bothered us, until we don't have to put up with week magnets anymore. We all grew up learning that is just how fridge magnets are. We were wrong, these aren't & look great too. Second was in my classic truck project to hold a modern 10" tablet in place for a removable Infotainment System & touch screen. Again these extremely powerful magnets worked better than expected. No falling off with bumps in the road or sliding down at all. I will buy more in different shapes, like spheres & clubes, just for fun to play with. They are coating in nickel or zinc & have a futurist metal look.
