DIYMAG Super Strong Neodymium Magnet, 40x20mm Rare Earth Magnets High Power Round Large Magnetic Permanent Disc Magnets 2 Piece

DIYMAG Large Neodymium Magnet Super Strong, 40x20mm . This is a very strong magnet. We use it to hold up roof pannels on a 4-12 & 4-10 pitched roof prior to screwing it down.Worked well. Be careful when using it or carrying it close to metal objects and definitely watch out around other magnets. It will jump around your hand and pinch or dam near crush fingers. Very strong not for kids.Need this size magnet for strength i recommend it for sure.

Brutally strong

These are super fun and strong. 100% recommend. If you are not experienced in playing with magnets, be careful they are strong. If they are not strong enough to unlock your stolen clothes, then a magnet will not work. They are not quite N52 but almost. Btw, you separate magnets by sliding them apart, you can't pull them apart. Ignore the negative reviews. These magnets are the size advertised. Also they don't break as easily as some.

I bought a tigers jersey shirt from the store and I didn’t realize it had one of those ink tags on it. I had this top in my closet for months waiting for an occasion to wear it since it is white. I couldn’t take it back to the store cause I didn’t have my receipt still so I was searching for a magnet to take the tag off. I was shocked that it truly worked. I did it over the sink incase it busted the ink tag and I didn’t was my floor or anything else ruined it I made a mistake. But this magnet popped it right off. But be warned I wasn’t watching and it touched my sink and I had to pry it off by force. Also I would keep this in the box it comes in so that you don’t ruin anything by the magnet. Yes it was worth the money!!!!

The four star rating is because it chipped when softly dropped. It's brittle. Otherwise it is exactly what was advertised.

These worked awesome for what I needed them for. Zero complaints.Warning...don't let your kids play with these. Get a finger in-between then and they're in trouble. They probably couldn't get them apart, but if they did and get skin or a digit in them it's terrible. I speak from experience! They broke my skin and it took some effort to get them off.

DO NOT, I REPEAT, DO NOT put your fingers in between these magnets. Only issue I've found is that, if your not careful, the magnets will smash together, and sadly, they will break. This happened to me when I was initially opening the package. I did NOT realize that the magnets would be as strong as they are. I finally was able to pry them apart, and immediately after, they shot back together as I relaxed (kind of user error) and broke into multiple different pieces. So if you buy these, just be careful with them and try not to put them too close to eachother.

There's a magnetic phone case for schools to lock up phones during the school day. This does not open them. Awesome magnet. VERY powerful. It will destroy electronics if placed near it
