Review on MIKEDE 8-Pack Powerful Neodymium Magnets With Double-Sided Adhesive - Ideal For Fridge, Crafts, DIY, Science, Building & Office Projects - Rare Earth Magnets For Strong Grip by Jerry Delozier

So I originally got these to use as a stronger magnet for holding documents (Purchase orders that were awaiting invoices, purchasing lists, to-do requests, etc) at work. Where my desk is located, I have a shelf at about eye-level that has a metal crossbar, and it works as a spot to put stuff that I don't want to forget about. So I have this one magnet that is fine, until you start getting a few pages thick and then it doesn't work as well and I needed something with more oomph. I wasn't quite sure how strong these would be until I took them out of the box. After sticking to LITERALLY ANYTHING METAL in a 2-inch radius (no joke, it took 5 minutes before I could get enough pens and paper clips away so I could take the picture), I finally got them to attach to my tape measure, which I didn't even know was magnetic until these little guys came around.They are POWERFUL for how small they are. You could almost say they are aggressively magnetic! It takes some serious effort to get them apart, and heaven help you if you let them get stuck together without the little plastic spacer rings they come with. I had to get a little door panel tool to get them apart again without damaging the magnet itself. The downside (and why they sadly won't work for my particular application) is the size; approx. 1/16" thick and 1" in diameter, they come with 3M sticky pads that adhere to the magnet pretty darn well, but if you do go that route for an install/project, don't expect to get them out with ease. I'll find some other use for these guys, but I'm still on the search. 10/10 Great little magnets!
