TRYMAG N52 Keychain Magnets for Testing Brass, 2 Pack Black Neodymium Pocket Keychain for Purse with Strong Magnetic Rare Earth, Gold Silver Jewelry Ferrous Metals Test Magnet Hanging Keys Holder

Pros: Strong, lightweight, keychain, 2 ea Cons: none

Strong magnets work great for jewelry analysis. I found several fashion rings stamped 925 to be magnetic, which they shouldn't be if they're really 925 silver, including one manufacturered by a high-end name brand fasion designer. You gotta be careful. Easy check right on your keychain.

Handy. Affordable. Strong.

These TRYMAG keychain magnets may be small, but they’re definitely mighty! Perfect for anyone who works with brass, metals, or just has a habit of dropping tiny screws under the couch, these magnets latch onto metal with the enthusiasm of a dog spotting a squirrel. They’re lightweight and compact enough to clip onto your keys or tool bag, so you always have one on hand. The strong neodymium power means they won’t give up on their metallic mission easily—they’ll cling to anything metal like their life depends on it, making it super satisfying for DIY projects or testing. But beware: their love for metal knows no bounds, so if you accidentally drop one, it might just make a break for the nearest metal surface. Pros: portable, strong grip, and handy for small projects. Cons: very easy to misplace, and they can be a little too clingy with anything metallic nearby.

Not as strong magnetism as some other small magnets I own, but this is a good quality product. I use these all the time as a fire alarm tech, to test detectors. The Keychain is convenient for keeping the mag handy or attaching to a pole. They could be stronger, as I have others that are, but for the price to get 4 of them, its a good value.

I bought these for the men in the family and they like them.I kept one for myself!

Super Strong Magnets specially connecting to each other.

Not as strong as I thought they would be, but if you just need a magnet I think it's fine
