Super Strong Neodymium Disc Magnets with Epoxy Coating, Powerful Permanent Rare Earth Magnets 1.26 inch x 1/8 inch, Pack of 10

I use them not permanently to attach things to each other. For example, I attached fancy lights on the back of my monitor. I did not use the double-sided stickers that came with the magnets. Those are simultaneously very hard to remove and do not hold for long because of the minor heat coming from my monitor. The magnets themselves are fragile, which is annoying. You should not let them close to each other without protection, or else they will snap together and either dent or break each other.Beyond that, they had a strong attraction and served my needs well. I glided four magnets on the back of the monitor and two on each light. I had to be careful with the polarization, else instead of attracting they might repel each other.

Extremely strong. You have to be very careful taking them apart when you get them. Do not pull them apart…slide them apart because they will break easily. I broke one as soon as I opened them.

Super Strong magnets but as others mentioned they break easily.And when I say break, I mean shatter.Once I get them out of the packaging and on the board where I use them they are great.

The magnet is super strong!

These things are strong!!!!!!!!!!. Nice finish
