Great Magnets - Incredibly Strong!

Reviewed in the United States on July 25, 2016

Verified Purchase

I needed something strong enough to hold mosquito netting to the inside of my car door, and had previously purchased some magnets from WalMart that were woefully inadequate. I was unsure when ordering these, but they arrived promptly and are incredibly strong -- so strong that it's almost hard for me to separate them. They seem very sturdy and will work perfectly for what I need them for, but when handling them they do "slough off" or leave some sort of dark residue on my fingers (but it is easily brushed off.) Also, I do think that if dropped, they might shatter... the good thing is that they're strong enough, I don't have to worry about them coming loose and falling on their own... I just need to be sure not to drop them :)

Strong magnets I use on my fridge to hold things there.

Reviewed in the United States on July 31, 2016

Verified Purchase

Really like my set of magnets that came neatly packed in a little box. These are robust magnets. Yes they have dust on them but you can just wipe them off with a wet cloth before using them and then it is okay. I just use mine to hold up bunches of paper stuff on my fridge and they are strong and do an excellent job for that. It can easily hold a good 10 sheets or more of paper 8 x 11 on a fridge very securely. I don't know if they break when dropped because I have never dropped them for how I use them. Mine have always lasted for years and still really stick to the fridge, real good!

I use the magnets for work to hold my labels and paperwork to my forklift. It will break over time when it keeps slamming onto a surface but I tape the magnets to provide cushioning and it keeps the magnet from falling apart.

I use it for other things too: make my box cutter magnetize to the forklift. After I tape the magnet I superglue it to the knife.
I tape a pen/pencil holder to it. That way I don’t have to keep opening and closing my storage box.

Be careful not to get your fingers between two magnets. They're powerful. NOT for children!!! They also will break if dropped on concrete. But if you're careful, these may be just the thing for your project.
