I love the strength of the magnets. The only issue I had is 1 magnet arrived broken. The magnets come in a cubic container, but the magnets are able to move around within the plastic case. It seems they that I was have broken that 1 magnet. I purchase the “small 30x10x3 mm magnets”. Great price. They do the job I need them to do. You can see the crack on the 1 that got damaged while in transit.

These magnets worked great for a window shade project! Super strong magnets and the adhesive pads worked well too. I bought the silver coated version and had no issues with chipping or breakage. No drilling or other tools needed to complete the project, with some spare magnets left over for another use. 100% satisfied!!

One of the magnets broke while I was opening up the package. I pulled one magnet apart from the others, but it slipped and was magnetically pulled back to the others. The force was so strong that it snapped the one magnet in two. So, pro is that the magnets are strong. Con is that they are brittle. — 5/13/26 Update — The seller contacted me of their own accord and offered to issue a refund. Given their initiative to ensure customer satisfaction, I’m updating my review of the product from 3 to 4 stars. I’m also leaving a 5 star review of the seller themself.

I got the really small ones because I just wanted some adhesive backed magnets to put things on my refrigerator. I was shocked at how strong these little magnets are. I got my finger between two of them and it slightly smashed my finger. The adhesive part seems to be working just fine. Granted, the items I'm hanging are not heavy. But again, I've never seen magnets this strong.

to begin with i ordered these to put up signs to keep others from dumping trash into our dumpsters. they take and swap out those dumpsters every other week. i needed magnets for the signs so that i could remove then and then put them back up once that is done. these magnets looked like they would do the job. on arrival the first thing i noticed was that the top couple of magnetics were smashed into tiny pieces? so there is no solid metal these are a composite material. they are similar in size to quarters both in diameter and depth. stacked they actually look like a stack of quarters not magnets. but as said some were smashed up. this is where i found how powerful they are. trying to get the broken bits off the rest of the magnets was not an easy task by any means. fyi due to how breakable they are REMEMBER the 6" rule. if you get two of these within 6" of each other they'll literally jump out of your hands to 'grab' each other. no wonder they put small plastic dividers between them so you can pull them apart. therein lies another problem. they do not come with adhesive already applied to the backs. instead they send some generic looking round glue tabs. even after letting these sit for awhile before putting up the magnets are far too strong for the adhesive to hold up when the item is removed. at most i was able to lift the sign off once before the magnets ripped off the glue tabs. simply not a good design for magnets intended to be removed with whatever they are attached to. the magnets that did make it unbroken cannot be used for their intended purpose all due to the glue/sticky tabs not holding up. so between the fragile nature of these and the lack of adhesion with the glue/sticky portion i can't recommend these. they are amazingly strong magnets but with two too many flaws for me. they might well work out for others which is why i gave them a three star rating and not two. FYI amazon customer service as usual was great. i let them know about the broken magnets and the issue was resolved in under five minutes. i appreciate that very much!

Strength of these magnets is excellent!! They are actually so strong it can be hard to remove them from the surface. Nice thickness and not at all expensive for how easy and well they work. I did realize a problem that should be noted. The magnets can crack and shatter if allowed to snap together too sharply. I did not realize this would happen when I was removing and stacking them together to put away after use. Their magnetic field is so strong I was just letting them snap together into a pile. I did not know several had cracked until I picked up the stack and saw crack lines on some of them. I am still very happy with them. I will just be more deliberate in not letting them snap together sharply. Due to the ability to crack I have given a 4 star rating.
