MIKEDE 4 Pack Strong Neodymium Magnets Bar, Heavy Duty Rare Earth Magnets with Adhesive, Powerful Rectangular Magnetic Bar Magnet for Crafts

Okay, these suckers are strong!

These are amazingly strong, they’re perfect for my project. One thing to consider, since they are so strong do not let them slam together or they will break and shatter. I accidentally did this. I definitely recommend these if your looking for a strong magnet

Two of the four broke the first day. They’re strong but at the same time fragile.

dropped separated just two inches from wooden table, two of them pulled together and exploded producing a bright spark and multiple fragments. yikes. suitable for specific tasks but be careful.

I was looking for a strong magnet to hold meal plans on my refrigerator. These are certainly strong but too strong to be comfortably used. Tough to get apart and then they knocked together by the magnetic pull and broke half of them. I recommend something where the magnet body is more durable and less strength in the magnet.

good magnets for my project if you slide them apart they won't break

These are really nice magnets, they look great and they are very strong. The only issues I found were that, being a thin bar, they will break very easily if you let it pull itself quickly against a metal surface or another magnet. I broke one just pulling it off the stack and then trying to put it back on the stack, it snaped in half length wise. The surface looks great but the black is very easy to scratch, won't matter for most applications. Neodymium Magnets are always fragile so I'm not going to take a star off, you just need to handle them with care and realize they are strong and will jump out of your hand quickly.

Upon opening package and simply trying to separate the magnets, resulted in a crumbling of the magnets in a shower of SPARKS 🔥. Definitely a safety issue I am returning and seeking a different product from a different supplier
