MIN CI 18 Pcs Strong Neodymium Magnets Ring Disc Heavy Duty, 0.98 in Round Permanent Rare Earth Magnets Hole, for Cabinets Cruise Crafts Decorations Science Industrial Screws (25 x 3 Hole 5 mm)

So strong hard to control and can slam back into each other breaking into sharp pieces.Also keep away from electronic devices like phones as they can wipe memory and disrupt speakers and more.I mounted these in alternating polarity on a 5 inch bolt (took almost two packs) to be used under mattress to dispel pain from injuries instead of pills. It's said to disrupt the pain signals in the body. And I find it does work.

it is exactly as shown. small magnet with a screw

Good and strong. They are difficult to separate but great hold and very functional. Works well for garage banners and fences.

Have these on all my rc drift cars. They are the perfect strength. Not too strong so the body rips if you pulled it and not so weak so that the body dismounts from minor bumps on walls/rails.

Very strong magnets, a bit hard to remove but doable, I needed a strong hold for a project and this fit the bill. Will buy again .

It's like you were expecting a full size mountain bike and they sent you a tricycle made for a 3 year old lol. These are tiny isles magnets that were sent in a box 60x to big.

Work great. Hole and countersink accurate, good hold.

They’re extremely weak as a magnet magnets much smaller than these without the hole in the middle work much better. They’re also very brittle while you put the screw and you have to be very careful not to break the magnet and that is by using a regular screwdriver hand controlled Terrible item. Worthless
