LOVIMAG Strong Neodymium Disc Magnets, Rare Earth Magnet with Double-Sided Adhesive for Fridge, DIY, Building, Scientific, Craft, and Office Magnets - 1.18 inch x 1/8 inch, Pack of 12

I got these for a new mini-fridge. Specifically to hang up some mini-posters that I had covered by polycarbonate plastic sheets to protect them. While it took more magnets that I expected ... including add some of a different variety entirely at the bottom ... I don't blame the magnets themselves. The previous mini-fridge had a metal exterior. This one doesn't. And, the magnets' description had said that they worked best with highly magnetic materials like iron; that steel was less magnetic by nature. Additionally, the front of the fridge has a subtle curve and the 12"x18",3mm plastic sheets, being the same thickness of the magnets, further lessons their strength. So, I'm fully aware that my particular use is less than ideal ... and that, when just used directly on a poster without the plastic, they're extremely strong. But ,what I wanted to provide feedback on was the steps the manufacturer has taken to address past consumer complaints about receiving broken magnets. In those cases, it looks like magnets were being shipped in a tube ... all in line with a separator". Their current package ... both for the 6-packs and 12-packs ... now has 6-magnet groups .... in a plastic, horizontal tray ... where each individual magnet has a slot in the tray to hold it securely and to protect it. While the separators are still provided, they aren't needed this way to keep the magnets separated and each magnet can easily be removed from its slot without interacting with the others. It's always nice when companies do respond to such past feedback to ensure they are providing the desired level of quality to the consumer.

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.

Super strong and easy to use.

These magnets are verrry strong! I'm using them to hold a tarp on the top of my old truck, which leaks. They work very well. The tarp won't blow off. However, the disks are very fragile. I made the mistake, when I unpacked them, to lay them fairly close together on a table. They jumped together into a stack instantly! The resulting impact cause several of them to fracture into very sharp fragments. Separating the disks was difficult since they were so strong, and dangerous because of the razor sharp edges. I ended up having to discard several of the disks.

MULTIPLE ORDERS requested for these. I keep using them in things and needing more. I did get some 3M heavy duty stickers in addition so I can relocate these or have more durable attaching strength. Wish the stickers provided were stronger or had extras.

These neodymium magnets are indeed powerful, perfect for DIY projects, fridge decor, and small crafts. However, they are quite fragile and can break if handled roughly or if they slam together, causing small, sharp pieces that can be dangerous. The adhesive also seems unreliable for heavier items, so glue might be a better option if you're attaching them to something. Be cautious, especially when unpacking, and keep them separated to avoid accidental shattering. Despite the strength, they may not live up to the "super strong" claim for heavier objects, but they work well for lighter applications.

So, I put these on my phone cases so I can record automotive repair content by sticking my phone wherever on the metal hood. One day, I was recording some tinkering with my secondary phone and...sort of... forgot about it....closed the hood, and drove home. I remembered with horror and ran to unlatch the hood. And THERE IT WAS. Phone safe and sound, had only scooted a little ways due to acceleration but still attached. Electric car conversion so luckily no heat. Very unintended product test but these magnets passed with flying colors. Highly recommend.

Ordered these for the refrigerator to hold up the ever-increasing number of childrens' artwork and school papers. They work extremely well; one magnet can easily hold four or more sheets of paper.The good part is that we no longer accidentally numb the fridge and send dozens of colorful papers al over the floor; the bad part is these magnets really do stick and can be challenging to remove from time to time.Overall, if you need strong magnets for whatever reason, these should easily meet your needs.
