Exceedingly strong! by J. Rock (CA, USA)  5 Stars

These magnets are really, really strong. They are also quite small and hard to separate from each other.

Is an excellent product if you want to know the temperature of metal and plastics while they are in the process of heating and thermoforming.

Incredibly strong and small magnets by J. B Kraft (Palestine, TX United States) 5 Stars
December 31, 2008
I bought these to attach a steel-housed shop light to the underside of a steel shelf without having to drill holes or attach screws.
These magnets are so powerful that when you attach them, you have to slide them around to get them off. Needless to say, they do a terrific job for which I purchased them, and can be removed or shifted as my needs change.
No doubt there is a lot of other "cool" things these can do for you. Keep them away from your computer, though.

Brittle... by P. Reilly  3 Stars

I bought these magnets for my daughter's science project and 3 or 4 split in half as she was separating them. They are very strong magnets and are fine once you have them in place.
