Keychain Magnets for Testing Brass, 2 Pack Neodymium Pocket Keychain with Strong Magnetic Rare Earth, Gold Silver Jewelry Test Magnet Hanging Keys Holder

FABULOUS for cat eye polish!

Hooked on my work key ring so I can activate the E-Band monitors used for Transport. It’s works great. Plus it makes it easy to check different metals when not working on the clock. It is also a very strong little magnet, can use it to hang my keys eye level in the shop.

Very handy! Works well!

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.

Great size, strong magnet, small

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 have bought these in past and the magnets seem to be weaker now. I suppose if just have a few keys it will be just fine but if you put any significant amount it is knocked off the metal very easily. However for the money still okay purchase. Only the silver ones though the black ones are for sure weaker.

Great little magnet for caregivers for resetting life alert pendants. Fits perfect on the keychain and small but effective . Will be purchasing more soon.
