Rare Earth N52 Neodymium Pocket Keychain Gold & Silver Jewelry Test Magnet

Bought this (2nd one) to help in verifying coins if they are real or fake.

Be careful with this Amazing Magnet - it REALLY grabs the metal! Excellent Product

I needed a small magnet for a very specialized application - to retrieve the puck screen from my espresso knock box. This is perfect for that. The puck screen must not have a lot of ferrous material in it, because the magnet is just strong enough to retrieve it. That's not to say that the magnet isn't strong - it is. I stick it to the side of my espresso machine for storage and it takes some effort to remove it. Highly recommend.

You may find this review amusing. I have a medical implant device (a St Jude spinal stimulator implant). From time-to-time, I need to turn the unit on and off when I am away from home. There is a controller, but it's not convenient to carry that device around. Plus, the risk of losing the controller is a very scary prospect, since this medical equipment is very expensive. However, the St Jude people made the device so that it can be turned on and off with a magnet! This is very cool. However, the St Jude people supply patients with a magnet the is really too large and heavy and to in your pocket. This is not so cool. The Rare Earth N52 Neodymium Pocket Keychain Magnet is the perfect solution. I have it on my keychain, so when I'm not home I can always turn my unit on and off. You just swipe the magnet across the battery/current generator -- implanted in my right butt cheek! -- and the stimulator turns off. Swipe it again and it turns back on. I just love this magnet!

This little magnet is a jewelry enthusiast's dream! It's incredibly small but packs a powerful punch. I've been using it to quickly and easily test the authenticity of my jewelry pieces, and it's saved me from buying some potential fakes. it's gentle enough to avoid damaging delicate pieces. Its compact size makes it perfect for carrying in your purse or pocket, and it fits perfectly on my keychain for easy access.

This is very strong for it's size and is perfect for my use.

It can tell the difference between my fake and real jewelry. With my stuff 100% accuracy fake, 10, 14, and 18 k

Ever since I bought it, it is attached to my keychain. Great product, the magnet is strong: suits for testing jewlery metal / getting that allen key that fell into your motorcycle again...It even comes with a tiny condom that protects the magnetic part, which proved useful.My only complain is the sky high price, but for a 1 time purchase it is fine, and trust me, this one will last
