So why would someone need such a powerful magnet? Well, all my life, I've been fascinated with them. I'm still amazed that such a relatively small chunk of metal can have so much power. This is a palm-sized rectangular block with a silver finish.. not shiny and artistic, but not an eyesore either.I had wondered how this would be shipped without causing havoc in UPS or FedEx shipping facilities, but when the box arrived, I placed a steel ruler next to the box and their was no attraction at all. Upon opening the box, I discovered why. The magnet was encased in a dense block of foam which provided some insulation. I plan to keep this stored in the a same box and foam. As others have mentioned, this is not a toy. Fingers can be seriously damaged or broken if two of these babies are allowed to attract, which they will do violently. Others have mentioned that neodymium magnets can break or shatter. I've been very careful so haven't had that problem.The one issue with this magnet is that it arrived with a tiny nick in one edge. I doubt it was dropped (would likely have broken?), so was likely a little bubble or flaw that occurred during manufacture. Since neodymium magnets can corrode, I'll still place a little clear polish over the spot to protect it, in case its protective finish didn't fully cover this little spot. No problem. It doesn't impact the functionality of the magnet, so still 5 stars.So how strong is this baby? Advertised to have 600lb pull. While I wish I could demonstrate its strength by lifting an anvil, I just gave my last one away :). So instead, tried it on a metal wheelbarrow. The little block is too slippery to hold in bare hands, so I wrapped it in a piece of vinyl cloth to get a good grip on it. See pic... lifted with no difficulty at all! Next I held it underneath my wooden desktop, about 3/4" thickness. Metal items were attracted to that spot on top of the desk, through the wood. Fun!! Be careful, though, not to get it near computers, credit cards, etc.So what did I get this magnet for? I live near a fairly large community lake. For years I've been wanting to go "fishing" with a magnet to see what folks have dropped into the water. It will probably be junk but I'm looking forward to finding out. (Will have to rig a pouch with rope to keep from losing it too.). And I have the hard drive from an old computer that I recycled. I held onto it, not sure how to erase the info before recycling. This magnet will do it!Whether for fun, practical purposes or science projects, this magnet is awesome!

This magnet is EXTREMELY powerful.... this thing can chop your fingers easily if handled inappropriately. It all depends what metals you attract it to. If you put your keys next to it it will attract them but you can pull them off more easily since keys don't have much metal, but if you put it next to a solid metal weight, not even Hercules can pulls this thing off. I even dropped it on the floor from 4 ft height, not even a scratch, when other magnets out there would shatter. This is not a fake review, I love science, I saw this and bought it to fulfill my curiosity, it did more than that and it was worth every penny.

Holy cow. When they say "super strong", believe them. This is not a toy to be trifled with. This is almost impossible to separate from other N52 magnets or metal surfaces. Could hurt your fingers if you are careless. Great for my magnet collection.

This is not to be trifled with.. This is not a childrens toy.. This thing is powerful enough to crush your fingers if they get in the way of this and some metal!With that being said, it's AWESOME! You can pin a text book to your fridge with this thing if you want.. You can use this to wipe out magnetic media. You can use this to pull a metal splinter out of your body if you want. It's that strong.CAUTION though, with this in your pocket you may find 'random' metal objects being dragged toward you - and I am not kidding. It's fun though.. Also being in IT, this is amazing for 'wiping out' USB sticks and memory chips for security reasons.. Worth buying JUST FOR THAT!Remarkable, and recommended for all curious, scientists, engineers and anyone looking to have a REAL magnet.

Be VERY careful with this magnet. You will not believe the strength of this thing. My son stuck it to a 35 pound dumbbell and it was all I could do to get it off. If you "spin it or try to flip it" it can pinch the heck out of you. The attraction is insane. Do not play with this thing, we have to keep it in it's box it was shipped in because it literally wants to stick to everything metal.

I purchased two of the N52 Neodymium Magnets from Magneto Inc. and the company/magnets are awesome! The magnets are powerful and they are just as they were listed in the Amazon description. Great product!

Great price, fast delivery, and wicked, ÜBER strong, magnet. If you’re finger’s hovering in indecision over the <Buy now with 1-Click> button, just click it, you won’t be disappointed.I’ve been interested in magnets for about as long as I can remember. There’s just something fascinating about the invisible power they’re able to exert, and none of the magnets that I’ve owned in the past 40 years can hold a candle to this thing.Truly a rectangular block of awesomeness; order it and be amazed...

This magnet comes very nicely packaged and protected. This magnet is super awesome, it is very strong. There are endless uses for his magnet, it's small and light yet provides a lot of power.
