Super Strong Rare-Earth RE Magnets (12mm x 1mm / 100-Pack)

Pros: The size is very nice. So you can use them in plenty of projects.
They are very strong for the size.
If you need more atraction you can simply add some more.

Cons: If you are not carefull they can brake in two or even more pieces when they contact each other. Once they are glued I guess they will not brake.

Other: I will still buy them if I need more. I bought a 100. And I will find several uses for them in the near future.

Pros: They're great for attaching random stuff to your fridge or other objects.
When you combine all 100 magnets into one bar you can move a magnetic ring (like sku.22439) at a distance of 10 cm. When you put multiple magnets next to eachother on a flat surface it can be quite difficult to remove the object again.

Cons: Although the magnets where stronger than I expected from other reviews, you still have to watch out if you don't want to break them.

Other: Great fun to play around with. They where stronger than I expected from the other reviews (when it comes to their magnetic strenght and to breaking them).

Pros: They are small. They are inexpensive per unit. They are awesome. As other people stated, these magnets are really, really strong compared to their size. You get a hundred of them stacked together, and they are even hard to get apart without considerable effort.

Cons: They are small - and really, really fragile. By which I mean, they are EASILY breakable and WILL do so by themselves. Put a single magnet somewhere, pull it in using the remaining magnets and you have a 50% chance of breaking that magnet just because it impacts on the other magnets with such force that it will shatter into two or more shards. I'm serious.

Other: Don't underestimate these magnets. They are strong enough to interfere with your electronic devices, stay away from your PC and phones. Even though they are forcefully strong, they are equally fragile and will break if you use them. But that's why you get a hundred of them - and the price is quite fine for that amount.

Pros: -The magnets are very strong! I can even change the direction of my ball compass from about 0.5 m away!
-They are rare earth magnets... I never saw this product anywhere else, so I guess it makes it quite rare. I think they are a Nd alloy, not sure what else they use in it.

Cons: They are a bit small... But they came in the size they are announced, so not really a con... But I suggest some bigger magnets, like 2.00 mm in diameter.
They break if they fall or collide with one another too hard.

Other: If you like magnets and science stuff, get them. With a larger diameter, for extra fun!

Pros: "Super Strong" is not a lie. Those tiny little monsters are really strong, especially for their size. They are probably made of neodymium, which makes them most powerful magnets in power-per-weight ratio. One magnet (which is one cm in diameter) can be compared to about ten times bigger ferrite magnet.

Cons: Some people claim they can be easily broken, but it didn't happen to me yet. So no cons for now.

Other: If you need a small magnet for some reason, buy it. Totally worth it.

Pros: These are very strong magnets. As they are quite thin, the 100 piece pack is surprisingly compact and small. You can use them in many ways, my main motivation was to make customer fridge magnets, and holding few maps on the wall. Even a tiny piece from a broken plate can hold A4 size paper!

Cons: Few of the shipped magnets had rough or not completely round edge, but it does not matter for me at least. Also as they are so thin you need to be careful that they will not break. I put on carefully on the table, and as the rest of the pack is so very strong, it pulled it up, breaking it to pieces. That is how I learned about the strength of the tiny fraction...

Other: Very good and strong magnets for your own DIY projects, too thin to really play around, just remember to handle them with care, especially when you have many of them nearby - they are so strong.

Pros: - They really are strong magnets. - Very useful to have around the house. (see thoughts). - Seem to be retaining their magnetism after a few months. - Cheap compared to other places.

Cons: - About 4 or 5 of the magnets in the pack were 'duds' (only about 1/4 of the strength of the rest.) - They break really easily, if you split a stack in half, and aren't gentle when you recombine the stack, it may break a magnet.

Other: Very useful, I will probably order more (maybe different size) magnets to have around the house. You never really think of uses for magnets until you actually need them. They saved me having to drill holes in my window frames :)

Pros: there are quite many of them they are very powerful even using only 1 of them when using all of them they get much more powerfull. have shiny coating witch is hard to wear off. really cheap came full 100 pack I don't think its Neodymium magnet but still good one have many ways of usage

Cons: thin so when using only 1 it can break quite easily. 2 were wrong ones (only little round peaces)

Other: Good item. you can glue it to some item and use for example as fridge magnet great item really recomend it

Pros: The size is exactly as DX mentioned it ( 12mm x 1mm ) Very strong from 100, just one was chipped on a side ( very small crack ) Good packaging ( no problems if stored on a metal body )

Cons: No cons for this

Other: Very nice! Very satisfied that just one was slightly damaged, in contrast to other reviews where 2-3-4 were damaged.
