MIKEDE 20x2mm Neodymium Magnets, Small Strong Magnets with Adhesive Backing, Black Round Fridge Magnet Strong Magnet Heavy Duty, Rare Earth Magnets for Whiteboard, Office, DIY, Craft 15 PCS

Magnets were exactly what I was looking for! They are slightly smaller than a quarter but thick enough that I’m not worried about them breaking. They are crazy strong anything metal in a 2 inch radius is going to get pulled in and stay there. And if you get two magnets stuck together it’s difficult to get them apart because they’re so strong. Due to their small size I’ve been able to use them in a variety of places, in a wallet, on a fridge, and just for organization. The adhesive is strong but not enough to damage whatever you put it on. The repelling strength of them is also pretty strong. I’ve been using one as a door stop with another magnet and it’s preformed great. Overall would recommend if you’re looking for decently sized strong magnets.

Magnets are very strong once you have their polarity straight. Double sided foam tape could be stronger but I used two of them and it seems to have worked, so far. Used one on door stop and one directly on door. Works very well.

You definitely get your moneys worth with these magnets. I bought them for a project to make a makeshift speaker. I basically used copper wire, card-stock, an audio adapter, these magnets, and my phone. I was able to make a speaker, and you could hear it and everything. The point is these magnets work, and they are not super delicate like some magnets out there. They also work as refrigerator magnets, and I can post papers and other stuff on the fridge without stuff randomly falling off. Most of the other magnets on my fridge are just common magnets, and they are so weak that stuff falls all over the floor all the time, then the cat starts playing with it, drips of water gets spilled on it, and it’s just annoying. With these magnets, it’s no trouble. Very strong.

I purchased this product with the intention of using it to mount mini blinds on my metal door. While other reviews suggested it would hold the blinds securely, I found that the magnet wasn't strong enough. The magnets themselves are of high quality and come well-packaged, but they were unsuitable for my needs. I ended up opting for a magnetic mini blinds set from Amazon, which worked perfectly.

These magnets are exactly what I needed. The only "problem" is they are so strong it is very hard to separate them should they come in contact with each other without something in-between them. I was able to separate 4 out of 6 easily enough by sliding them apart but the last two weren't cooperating so much. Any use of a thin metal like putty knife or flat head screwdriver to wedge apart didn't work as they would stick to the top of the magnet when trying to push between the two magnets. I finally used a catfood can lid (aluminum) and it worked very well. It was perfect, thin enough to slip between the magnets & separate them.

ADVANTAGES:*The defects (dents, craters, tarnishes) are slightly less (better) than the average when compared against all other Chinese-made neodymium circle magnets*The strength of pull is adequately strong but not excessively strong*These magnets won't crack (shatter) any more easily than the average when compared against all other Chinese-made neodymium magnetsDISADVANTAGES:*I received 19.05mm x 2.39mm circle magnets when I ordered 20mm x 3mm size circle magnets (19.05mm is exactly 0.75 inches, while stacking 2 magnets on top of each other makes them exactly three-sixteenths of an inch tall; thus, 1 magnet is exactly three-thirty-seconds of an inch tall)

First, these are great and quite strong for their size. Also, double sided tape isn't magical, sand both surfaces a little first and then try. If that still doesn't work, use epoxy (sanding first is key with either option).The important part -Ignore every low review that says they shattered. There is no brand of Neodymium magnets that won't chip or shatter when you let them snap together. They are ALL fragile.Slide them together slowly and you should be fine. Just know, at some point you're probably going to chip them.Regarding the videos of them sliding down the side of a fridge: you have two super smooth surfaces against each other, where there's a lack of friction, there will be sliding. Get some paper sticker sheets and stick them to the magnet so that there's some grip.It was irritating reading all those reviews and seeing the pictures. I NEVER write reviews. On this, I just had to set the record straight. Maddening!

Careful! These can pop a metal filling out of your teeth, snatch the hands off an old school analog watch and can wipe all the data off a memory card or other RAM Device! And don't catch your finger between the magnets and the metal you stick it to! They can do a serious finger pinch if you're not careful!These are the strongest magnets I've found! The could hold a note on your refrigerator in a hurricane! Don't let small children play with these unless you really don't like them!
