They’re smaller than what I first thought but that’s good, I didn’t want them to be so big. They’re VERY magnetic, hard to pull the magnets apart so that shows how good they are.

Pretty strong magnets with great quality. Used these in a 3d print project for Mickey Mouse ears for a Disney trip. We’re to the right size as described. Never had an issue with the magnet strength, the ears stayed in place the whole time.

These are very small, definitely read the dimensions. I purchased knowing how small they were, however they are very difficult to manoeuvre. They stick together and will pull back together when trying to use. On the bright side they are obviously very strong for their size.

Works well—strong magnets. Used them for polymer clay fridge magnets adhered with resin, and they hold great.

They work like magnets should. Good grip and not expensive. I did have one that broke in half so I’d try not to drop them.

They were very weak for my application. I can’t seem to find a strength claim on the listing so I can’t take much away.
I’ve worked with a lot of N48-N52 magnets, and theses are one step up from black fridge magnets. Once I doubled them up it gave me almost as much holding strength as an N48 2x3x100mm magnet broken to about 20mm length. So it is very weak for this type of magnet, but also significantly more than weak black fridge magnets. 2 of these stacked actually start being about what I’d expect for an N48 magnet of the same size, maybe even N52. Note that they are brittle, I cracked one with a slight offset while practising safe handling best practices (I guess not best practices since I slipped). But the distance separation was maybe a mm and I broke the one magnet. That isn’t unheard of for these types of magnets. But places these at the lower end of quality in my experience. Could be a batch issue.

I was using this to hold up a light plastic valance on 2″ blinds, and it took 2thickx2wide to get the support to hold maybe 200g of plastic vertically (likely less). For a Neo magnet, with a 0.2mm separation at 15x3mm, this was weak in my experience. But this is not advertised with a rating so “strong” means less than rating worthy. It is sufficient for most light use cases.

Would I recommend it for the price? Nope. I bought custom N52 magnets for roughly the same per square cm price 5 years ago, and they vastly out perform these to an embarrassing amount. Amazon may not be your optimal source of magnets, but if you just need a little strong, or are willing to stack them, they are acceptable. My advice is you can likely find better, just not on Amazon having tried, for maybe $10 more for the same or more count. Convenience tax is very high on these…but we all love the convenience.
