I use it as a chim for CR123 batterys in a 18650 charger and they work great for that. Cons: They break very easy

Pros: Small but quite strong magnets cons: Got some 3 or 4 damages after inspecting. Quite supprise with the magnet. Did not expect to be that small even they state the size. Nice and strong small magnet.

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...

But I suggest some bigger magnets, Nothing to say 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). Read more

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 ) No cons for this Could be cheaper :) Very strong, strength grows when adding more magnets Good finishing and get... 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 ) No cons for this Could be cheaper :) Very strong, strength grows when adding more magnets Good finishing and quality You get a lot of magnets :) ( 100 ) Can be used for DIY, sticking photos on the fridge, door, etc Easy to break Very nice! Very satisfied that just one was slightly damaged, in contrast to other reviews where 2-3-4 were damaged. Read more

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 thin so 1... 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 thin so when using only 1 it can break quite easily. 2 were wrong ones (only little round peaces) none Good item. you can glue it to some item and use for example as fridge magnet great item really recomend it Read more

(see thoughts). - Seem to be retaining their magnetism after a few months. - Cheap compared to other places. - 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. 4 or 5 of the magnets were not as strong as the rest, but I think of it as 95% perfect magnets and it's not really a problem. I use these magnets as household tools, currently the magnets are holding heavy blackout curtains onto my window frame (we have 23 hours of daylight at the moment, blackout curtains are needed so I can sleep). They hold the heavy curtains up with no problem. I also use them to hold certain items while I am gluing them together. 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 :) Read more

These are very strong magnets. As they are quite thin, the 100 piece pack is surprisingly compact and small.

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! 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... 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.

"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 I... "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. Some people claim they can be easily broken, but it didn't happen to me yet. So no cons for now. I wonder why they don't use them for souvenir magnets. I collect magnets from all over the world, and only one of them uses this kind of magnet and not a weak ferrite or even weaker plastic one. If you need a small magnet for some reason, buy it. Totally worth it. Read more

But I suggest some bigger magnets, like 2.00 mm in diameter. They break if they fall or collide with one another too hard. Nice pack of 100, you can give some to your friends!! If you get 2 and clamp them on your ears, you get a cool earring... haha If you like magnets and science stuff, get them. With a larger diameter, for extra fun! Read more

Strong magnets even tho they are only 1 mm thick. you can add two or more together to get added strength, but try to keep them from smashing together. Magnets like these will have a thousand uses.

Strong magnets even tho they are only 1 mm thick. you can add two or more together to get added strength, but try to keep them from smashing together. Magnets like these will have a thousand uses. They do break easily when you play with them..... but come on, they are magnets.. how can one not play with them :-) I think maybe 3 or 4 of them broke purely by accident when handling. I bought a set of these to mount all my screwdrivers in one place by drilling a hole about one or two mm in a wooden bar, then I put some glue in the hole and pressed the magnet in. It is able to hold a large screwdriver in place if you put two magnets for added strength. i will be ordering another set now to keep the biggest ones in place safely. Good purchase, i dont know if the price is the best but its good enough for me to order more. Read more
