TRYMAG 25 Pack Super Strong Neodymium Magnets, Heavy Duty Rare Earth Magnets with Double-Sided Adhesive, Powerful Bar Magnetic Strips for Crafts, Fridge, Garage, Kitchen, Science, Office - 40x10x5mm

Excellent, very powerful magnets , good quality !

These are strong magnets and work very good for holding items in place. The only thing that may be week would be the sticky tape may not hold if the area is not clean when putting them on.

Magnets are nice and strong, and will do the job I bought them for, but the foam tape is a little on the weak side for them, have had a few fail to hold in multiple ways, had the sticky part of the tape fail from the magnet side, the sticky part fail to hold onto the plastic box. And the foam part of the tape fail and separate with the sticky parts still attached to both the plastic box and the magnet. Project. Used 4 magnet's to the plastic base that holds a 20v tool battery. Then the magnet's hold it to the side of a metal toolbox. I added some craft foam strips in between the empty spaces of the magnet's that is just a bit higher than the magnet's. It squeezes down when attached to the metal toolbox, and prevents it from sliding down the toolbox.And yes I did prep and clean both the magnets and the plasticbox, to give the foam tape the best chance to adhere.Will just have to get some heavier duty type tape.

Hella strong lol

Unbelievably powerful magnets for their size. Used an old shower curtain to cover swamp cooler using these magnets.

I like the size, and work well until they break into multiple pieces.

Great magnets, but I can’t remember why I bought them. I think that means I buy too much stuff.

Really fragile, magnets work but have no durability, its like why am I buying this crap from China??? My bad. Half of them broke when they where magnetised about 3 inches away. Not even worth to return, I would avoid
