Tools and Hardware Reviews of Magcraft NSN0607 1/2-Inch Rare Earth Cube Magnets, 4-CountCustomer Review: Fun, but too powerful and brittle for any real use Summary: 2 Stars
I bought these for different two reasons: 1) to meet my legitimate magnet needs, and 2) as a toy. I think these fail at #1, but are great for #2. For actual magnet needs, these are just too powerful for most applications. It's very difficult to separate the magnets from one another, they connect with their attractions VERY forcefully, and they're very brittle, breaking quite easily. For example, I experimented with one as a fridge magnet, and it made contact with the fridge so hard that it actually scratched the paint on the door and chipped the corner of the magnet--and I was being careful not to let it slam into the fridge! These did do a good job at magnetizing screwdrivers, but again, it didn't take long for them to start chipping away and breaking.
As toys, however, these are great fun! I must emphasize, though, that these are **dangerous** and **NOT FOR YOUNG KIDS**, seriously, these can cause some severe pain. Even when I was trying to be careful, I hurt myself many times with these magnets. If two of these are attracted to each other and you're in their way, they can deliver a pinch you won't soon forget, often involving bruising and swelling!
So have fun with these, prepare to get hurt a few times, and keep them out of little hands. Overall, if you're looking for magnets as a tool or utility device, these probably aren't best for you. If you're a teenager or college kid looking for some silly fun, these can provide some cheap entertainment.
