Super Strong Neodymium Disc Magnets, Powerful N52 Rare Earth Magnets for Fridge, DIY, Building, Scientific, Craft, and Office Magnets- 1.26 inch x 1/8 inch (20)

They’re small but strong, and you have to stay mindful of their strength, because if you get them too close to each other, they’ll slam together and break.

Magnets were packed well for the shipping. These magnets might be small but they are very powerful. These magnets are GREAT!

These are some strong magnets so be careful not to pinch your fingers when you working with them. They will even hop up off the table to another you're holding at a surprising distance. They're priced reasonably and arrived in perfect condition due to the great packaging. The only thing I can maybe ding these on is their strength being claimed as N52. I have some of the same size and shape that are noticeably stronger than these. I purchased those a month or so ago on Amazon. The rating system used stands for Neodymium followed by a number to indicate the strength of the magnet. Higher the number the stronger they get. N52 grade neodymium magnets are the strongest magnetis commercially available at this time. I still gave these 5 stars because being rated N52 just means they have a certain strength in a particular range. Some N52 magnets may be stronger or weaker than others even coming from the same N52 batch produced. These may be weaker than some of the others I recently purchased. Is it because these are weak, or is it because I got a really good batch on that one order before? I do not know. without some costly equipment to measure them. The size, thickness, and shape all play into factoring in their lifting strength. Just do not expect these to lift a 50-pound dumbbell off the floor at this size of magnets. So are these magnets rated N52 accurate? I think so. Anyway, these are strong enough to do any task you would want these for as long as you are not asking the impossible. I have read a lot of reviews on Amazon that give magnets bad ratings due to them expecting the impossible from any magnet. If you need even stronger for your project, then double or triple them to increase their magnetic strength. Remember size matters with magnets. For these magnets at this price and strength, I would not have any problems recommending them to anyone. I know I would purchase these again if I need these size/shape magnets in the future.

Very strong magnets but break easy.

I use these magnets to hold a screen in place around my a/c unit outside. We have a lot of cottonwood trees around our neighborhood and the screen captures the cottonwood seedlings before they get rapped in the a/c fins. When the cottonwood seedling build-up thickens up, all I do s turn off the a/c unit outside and run a vacuum over the screen and it save me the time from having to disassemble the a/c unit manually clean the a/c fins twice a year.

These are strong little boogers. I can hardly get them apart to use them. And when I do, don't have them close to you, because they'll just clap onto each other again.I use them to hold my vinyl window covering on my RV

Magnets are nice and strong but several were broken

Strong disc used them to hold window blocking sheets in windows rather then the double sided tape tabs included no mess clean up
