MIKEDE 20 Pack Strong Neodymium Disc Magnets with Adhesive Backing Silver

These are a bit larger than a quarter. Flat and well made. The adhesive actually sticks to both the magnet and the item you are trying to attach to the fridge. Works great.

Everything about these is super: super strong hold, super adhesive discs, super shiny and polished finish. I became disabled with arthritis so I had to retire early, but I still have a very active mind. Thus, I have a lot of hobbies to occupy me. Most of my hobbies are aimed at keeping my fingers and hands nimble and providing a creative outlet. I make jewelry, I work extensively in metals and wire, and I do a number of needlecrafts such as cross stitch and restoring damaged vintage and antique linens and embroideries. I'm constantly dropping needles, pieces of wire, scraps of metal, etc. I have a magnet I use to help me locate dropped needles and other bits. I certainly don't want my cat to step on something or injest something harmful. The magnet I've been using is very strong. I got it at a fabric store for stowing pins and needles, or tacking patterns to metal clipboards. These magnets are at least 5 times stronger. I like that I can easily attach a long string or cord to one using one of the provided super sticky discs and just sweep it around my work area. They easily find my lost items even if they've become embedded in carpeting. I also sweep one across my body when I'm making clothing alterations to make sure I didn't forget or miss any pins. Yikes! The only problem I have with them is getting them apart. Just when i have one pried away -- victory! -- the others will snatch it back. Grrr. I love them. There are truly a million uses for them. Top notch.

Pros: Arrived on time. These were nicely pkgd. I’m happy they are Very strong magnets. They Are Exactly what I wanted for the back of my project. Cons: I thought they would be a tiny bit bigger in diameter than they are. However, I’m fine with these as they work great for my needs.

The problem with these magnets is that the magnetism is much stronger than the adhesive. Even following the directions of normal 3M double sided tape. You want to clean perfectly the surface where the 3M tape goes and do not put any weight on it for at least 30 minutes. I'd say 1 day to be safe. Even doing this the adhesive did not hold. I put the magnets on an electrical power strip that I wanted to stick to the side of my tool box. Brand new clean power strip, I placed the magnets, and did not stick it to my tool box until the next day. Once placed the magnets are really strong. I plugged everything in to the power strip and all seemed good. Within a day or 2, the adhesive had failed and the power strip was on the floor. So i decided to use 3M Super weatherstrip & trim adhesive (3M 08008), in place of the included tape. I repeated the same process, letting the adhesive dry for a full day. That did the trick. 5 months later everything is still holding strong. The magnets are surprisingly strong for their small size (like a quarter). The glue was not.

Excellent refrigerator magnets for keeping photos from falling off

They are strong magnets but they break. One shattered into three pieces trying to dislodge from another one.

What’s so rare about them? They work great!

These coin sized magnets are perfect for 3 D printed badges. The magnet along with a metal plate on the back of the badge, allows the badge to be displayed on a shirt without poking a hole in the fabric. When not being worn to a rally, the badge can be placed on the refrigerator door for storage and display.

Very powerful. One had a small chip in it so I'll take off 1/10 star.
