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...
Excellent company and staff by being honest, reliable super fast and polite. The product? Great Quality!
Highly Recommended

Buying magnets from Indigo Instruments is a seamless task. You get a human on the phone right away and your order is quickly and efficiently handled. Shipping costs are provided quickly which completes the task in one phone call. The magnets themselves are superior quality and always measure up to the task.
It's suppliers such as Indigo which make my job as a purchaser easy to do.
