Katzco Black Precision Magnetizer and Demagnetizer - 3 Pack - for Screwdrivers, Screws, Drill Bits, Sockets, Nuts, Bolts, Nails, Drivers, Wrenches, Tweezers, and Other Steel Tools

They work period, that is all that needs to be said, they really work. Thank you for selling them.

Exactly what I was looking for.

I got it to work a little, but only using the de-magnetize side, not the magnetize side. I watched the video and tried 2 units in the 3-pack. I've had no problem with the Klein orange one in the past, so I'm ordering one of those. Possibly just needs better instructions but I need to share with others and if I can't figure it out others on my team may also have issues.

I liked that these came 3 to a pack so I could put them in multiple tool boxes. they work to magnetize my screw driver bits.

Worked great

They used weak magnets inside the magnetizer. It works but different than what is showing in the product's video. It will takes as many as two small screws at once, and hardly work with small screwdrivers.

Works good, but magnetize and demagnetize are reversed.

Bought these and they don’t work.
