Strong Magnets with Double Sided Adhesive Backing

The magnets are great they work wonderfully. The double-sided sticky tape is awful. It’s not even that hot outside and the double-sided tape didn’t even last a day. Glue would be better, but depending upon where you’re going to put it, we had it on the dash of our vehicle. Did not stick.

Unbelievably strong magnet, but do have a habit of breaking in half

There is no joke in saying these are powerful magnets. I got mine 10 minutes ago and I couldn't wait to play with them like a kid! I got them for my metal embroidery hoop. I wanted something strong to really hold down fabric because if it shifts mid-sewing, it can be ruined. I read what the seller said about using the spacers, I was putting the 6th one back on the stack to set down and from at least 6 inches away the 1 disc slipped out of my fingers and snapped onto the stack. It was the most powerful thing I've handled with magnets! I didn't mean to do it, of course. Then it took forEVER to break the top 2 apart. I couldn't slide it forward. I finally got it, but I think I wore out my right hand lol! I did a hand test where I put 1 on top of my hand and the other on my palm. The strength was definitely weaker, but it held. I don't have my metal hoop yet to say how good it is for my purposes. But like a kid, I kept trying different metals I have here on my desk. I will NOT try this on my fridge because I probably won't be able to get it back off. These aren't complaints, these are compliments. 1 disc did come with 2 chips in the edge, but it seems stable, they are very tiny. I can't image being the sorter who has to pry apart stacks of these for customers.

These are a good size but don't seem quite as strong as others I've gotten in the past. I adhered these to the back of my digital thermometer, timer and measurement charts so I could stick them on the side of the fridge. None of these are very heavy but only the measurement chart stays up. The other 2 . . . which aren't very large or heavy at all . . . end up sliding down the side of the fridge within a few days.

These are some of the strongest small magnets I've ever used!

Very difficult to separate but they are magnets, very strong so you can, if you are not careful, easily trap finger between them so be careful. I have stuck on inside kitchen cupboard for my good kitchen knives work very well

Très puissant

Really strong magnets.

extremely powerful

So yes, these are very strong magnets and should be used with even stronger caution. They come in a cardboard box (see images attached) with styrofoam with a centre hole that each magnet is separated by a silicone/plastic type divider and the sticker adhesive on top of the stack of magnets. When separating the magnets it isn't easy, as many have already mentioned. Right out of the box many of them have tiny nicks in the magnet, not a big deal, we tested out 2. I attempted to pry it apart from the stack carefully, they quickly snap back if you're not quick. My son wanted them for a project, marble run, so these needed to be able to be taken off and on a magnetic board and these do not work for that purpose. These are meant to magnetize and stay put, otherwise the magnet stays on the board and comes right off the adhesive. Putting them all back in the box for return knowing these will not work for our purpose, the last one snapped quick in tiny pieces just putting it back in its place in the box. Majority of the piece cracked in a bunch of pieces attached to the magnet but one chunk went flying. Wild. I'm starting to think these are dangerous and it wouldn't hurt to have eye protection just in case one snaps into your eye, lol. Not funny though as I knew what I was working with, I was careful and still had a hard time. They are sharp like glass when broken. I feel like there should at least be a warning with these with the packaging about all things mentioned by those who purchased. I really wanted these to work but now we have to try a different approach. Also, the small piece of styrofoam that's was in the bottom, if someone isn't careful they can easily all slide out and smash when opening or taking it out because that small piece is loose and only meant to protect the magnets in the box. See images attached for reference. Hope this review helps someone.
