Strong magnets, slightly larger than quarter.

These magnets are super strong. They can easily hold a lot of weight. Mine are holding my phone to the side of my dresser. That's right, two on the inside and one on the outside are able to attach a phone to a wood dresser, assuming you have a metal plate on the back of the phone. One on the inside was not sufficient to keep phone attached due to the thickness of the wood. Have not had my phone fall due to the magnets once. Each time I take my phone off, I have to manually remove outside magnet because it is more strongly attached to the metal phone back than the wood cabinet. Easily reattaches to dresser because of strength of magnets..

The strongest magnet for the size that I have ever come across!

Apparently, I had no idea what a real magnet is. Then I got these. It's hard to explain how strong these magnets are for their size, but they are unfreakingbelievably strong! I though tit was odd they put plastic spacers between them so when I finally got the magnets separated and removed them, one of the magnets found the opposite pole of his friend and shot over to it at Mach 1. It scared me how fast it happened. These little guys can hold up pound for pound more weight than any other magnet I have used. I'm serious though, be careful so you don't get your finger pinched or smacked when you get these near a ferrous object that they are attracted to. This company has many options of magnets available in different sizes so look around and get what you need. These worked perfect for my engraving applications.

Incredibly powerful magnets

I bought these magnets to help hold a magnetic mount motorcycle tank bag. The manufacturer of the tank bag didn't use strong enough magnets. These babies, holy cow! If they were any stronger you couldn't get them apart. These are the real deal and only buy them if you have a need for the strongest magnets out there. In my use, simply placing one of these over the existing magnets at each corner reinforced the strength so much I no longer have any issues with the tank bag blowing loose..

If you're looking for a serious magnet...

Hah! Wow, are these magnets strong! Yes, I read that you shouldn't let them get close to each other (they arrive separated by a thick piece of plastic). I swear they were at least 4" apart, and wham! I had two stuck together - and pinched a finger in the process. And they are not easy to separate. I bought these because I have a nice ceramic emblem I wanted to put on the tailgate of my truck, but I didn't trust the two little magnets that were attached to it. I popped one of these on it, and slapped it on my truck. It's not going anywhere. These are super-strong magnets! (Do not let them get close to each other!)

Nice magnets

The red line to mark the POS. pole is a nice feature, and probably saved me from pinching my fingers a time or two. They come as pictured with the plastic washers separating them, makes it easier to get them apart.

Super strong magnets

They are strong!!! I already knew that Neodymium magnets were strong but it was my first time to actually handle them. They are strong and fragile IF they collide to each other, but I don't think they are that fragile if you drop them to the floor, etc. You can take apart them using a side of a table (without any metal part!) if they got stuck together. I had a bathroom cabinet that is always open slightly and that made me so annoying. Using 3M tape, I glued one of the magnets on the cabinet and another on the outside of the cabinet door. So the cabinet door is sandwiched in between two magnets, They are strong enough to make the door remain closed! I don't think I will use these magnets to put something on the fridge door though... They are simply too strong.

Super - finds nails faster than normal stud finders

Super - finds nails faster than normal stud finders. I super-glued a couple of these magnets to sawed off dowels, (make the dowels short so that their weight doesn't compete with the magnets searching). One of the things I like about using these is that it's possible to use one to find a stud line and just leave it there until you're ready to begin your project. Caution on separating the individual magnets upon receipt ... they are mega, as in hugely powerful - so much so that if you get two of them stuck together, it's a challenge to get them unstuck.

Holy magnet, Batman!!!!

Omg! We bought these for my daughter to use with "homemade magnetic slime"! If you need magnets that will attract an object 5 miles away, or never let something slip, these are the magnets for you! They are so strong that they are dangerous! I put one on my wrist and one on the back of my wrist, and they stayed in place! Be careful though, they are so charged that they can hurt you by pinching the skin (pic attached is the painful pinch)!!!! Great magnet for industrial uses!

Watch your fingers. These things are STRONG!!!

Holy Magnets Batman! These things are so powerful they are dangerous. Actually TOO powerful for many applications. They will easily snap together in your hands if you aren't careful and pinch the crap out of you. You NEED to keep the spacers between the unused magnets or they are hella hard to separate. BTW I am a 6 foot tall 200 lb man. And it takes WORK to get them separated when I accidentally let them get together without a separator. I can put one on top of my wrist and one below it and they will hold together through my arm snugly. I saw a few review saying they were TOO powerful. That's not a good reason to leave a bad review for "Most Powerful" magnets, right? LOL They are actually too powerful for what I bought them for. But I found several other good uses for them.
