Tracy Myerson: ...purchased N42 Neodymium magnets, they are the real deal...had previously bought magnets on Amazon that were advertised as N52, they were just another cheap Chinese fake....
Ron Bennett: Fantastic support and product. Beats Amazon price with real customer service...product was of the highest quality and exactly as described.
Peter Maran: Their Neodymium magnets are superb in quality and price; ...tools, magnifiers, tweezers, and so on, all quality made...
Always good quality and exactly as advertised. Quick delivery.
