works well
a simple tool for magnetizing screwdrivers. I don't know why I didn't get one of these years ago!

Simple, inexpensive, must have tool!
I purchased this last year, because it was mentioned on a podcast. I thought it was a must have tool, so I bought some more for inexpensive novelty Xmas gifts last December. They were such a hit, I bought several more for X-mas 2025. I like mine, and the giftees like theirs too. On the downside, I've bought so many that I don't know who all I have given them to. I'll have to come up with a different inexpensive gift for next year. I've been using mine for about a year and a half. I recommend it! I'll buy a couple of extras for ME to have in different places around the house.

Great quality product!
I was sceptical at first but this thing really works! Pull it through the bottom and the screwdriver 🪛 is magnetized. Pull it through the top and the screwdriver 🪛 is demagnetized!😄😄😄 Great addition to my Electronics Laboratory Bench.

Fine Tool, No Instructions
The tool works as advertised; however, simple as it is, it would benefit from use instructions.

Rapid and Strong Magnetization Effective demagnetization
I've been using this little magnetizer/demagnetizer from the Delcast brand, and I'm really impressed with how useful it is. It's a compact, solid accessory that fits perfectly in any toolbox or even in the pocket. It does not need batteries or electricity; it is a passive neodymium magnet, which makes it durable and ready to use at any time.

This silly looking thing actually works
First used on a screwdriver that had become demagnetized. Two slow passes brought it back. Also used it to demagnetize some stainless steel hose clamps that somehow get slightly magnetized during production.

Worries but it's weak. Best use for IT Pro's, not mechanics
Works as it should in both functions, but not very powerful. My old one that walked away and retired I suppose, was solid metal and could lift my torque wrench. This can barely stick to the side of my tool box. Great for tiny drivers for IT professionals, not so great for mechanics and DIY

It wasn't what I expected and I was disappointed with the poor strength of the magnet.
