Shipping Errors or Damaged Product
Shipping cost for returns will be the responsibility of the customer unless the parts are incorrect or damaged upon arrival. For shipping errors or damage, SuperMagnetMan will bear the cost to replace the parts and the return shipment for the incorrect or damaged product. Custom orders cannot be returned unless the parts are incorrect or damaged. For details on returning parts, contact our shipping department at 205-621-8841 or email orders@supermagnetman.com for instructions.

Restocking Fee
Parts returned at the discretion of the customer will be subject to a 10% restocking fee. This policy applies only to orders received from our online store. 

Packaging Notes
If possible, please ensure that all products are in their original packaging to avoid damage during the return shipment. The customer will be responsible for shielding the magnets properly so that the box or envelope is not magnetic at the surface. If a paper clip sticks to any side of the package  more packing material (sheet metal, foam wrapping, peanuts, etc.) or a larger box will be required. If the parts are not properly protected, there is no guarantee the return will make it back to us in its original condition, and a refund will not be issued.


If replacement parts are not needed, refunds will be issued for parts only once they are returned to our facility in the same condition they were shipped. This does not apply if the return is for incorrect or damaged parts. 

It is important to us that you are happy with your order. Please contact us with any questions or concerns.

Thank you for your business!

Always a fan, but somewhat fragile

I'm on my third or fourth black-epoxy N50 ring, which helps me daily hold small screws, differentiate ferrous and nonferrous metals, locate buried nailheads/studs, and current-check AC power cables. If I have one complaint, the epoxy coating is very thin and scratches/cracks off easily when the magnet is pulled quickly into contact with something attractive. Eventually my rings have all broken under impact after 2-3 years each, since the neodymium base is obviously a lot less tough/strong/hard than the iron and steel parts its banging against. However at the reasonable cost SuperMagnetMan offers, I still consider them an absolutely worthwhile, despite impermanent, investment.

Side node, I've tried magnet finger rings from other sellers/manufacturers, none are as strong as the ones from SuperMagnetMan, nor offered with the coating options.

Thank you, my N50R5910BE arrived and is perfect!
However, my N50R5930 which also came in is defective and has a coating defect, not quite a chip but almost a 2mm imperfection or some flaking in the coating. Please advise on what can be done to make this satisfactory. Regards, Dennis
