MIKEDE 40x40x20mm Neodymium Block Magnet, Super Strong Permanent Magnet Disc Powerful Rare Earth Magnets- One Piece

Fab, opens the school phone cases. Bought it just incase and my son accidentally locked his phone inside his after school one night. Worked like a dream. Really strong.

Very strong

Incredibly strong magnet, really attaches with some powerful force and takes a lot of effort to pull it off. Good price but quite a weight to it. size as described

It's a really strong magnet once on the fridge it was hard to get back off. I bought it as a back up to open the Yonder Pouch after reading a previous review. It does not open the pouch, it's not strong enough

I have no way of measuring how strong this is other than empirically against normal magnets and this thing ripped the keys off my Cherry keyboard. Be careful where you put it. It is seriously strong. This will do anything from find studs in a wall or keep a barndoor closed!

something drew me to this magnet! its very strong, be careful when handling but does an amazing job

Disappointingly, this magnet wasn't... well, magnetic. A very expensive metal disc. I may update the one star rating if the customer service for the return / replacement / refund is a worthwhile experience.

Excellent product, very strong magnetic field.

Very very strong model i really like it

Powerful. I use this magnet to find nails/screws in drywall. It will easily locate those, even the deep screws. As other said, it is brittle so be careful not to drop it or move it near another magnet - it will attract fast!

Very strong magnet. I use it for a big, heavy photo calendar on my fridge. Very strong and secure. Highly recommend:)

the magnet itself is of good size and pretty powerful, but i will be returning it for an exchange due to it being chipped and not new.hopefully when i receive the replacement and all is fine, i will rate it a five star.

Very strong. Worked great for what I wanted it for... Erasing old VHS tapes. Just be gentle with it, they are not durable.
