What Customers Say About our Neodymium Magnets
[Actual reviews done on Google Places]
Roman Teliszczuk: Purchased neodymium magnets for work. The quality, price, packaging and delivery were excellent. I highly recommend Indigo Instruments.
Mark Elliott: Great website especially the dimensional and polarity information. Magnets arrived quickly and were as expected. Used to replace weak door alarm sensor magnets.
Ron Bennett: Fantastic support and product. Beats Amazon price with real customer service. After online order was placed, they called and and asked if I had any questions and gave clear instructions on pickup process. Order was ready and in stock and the product was of the highest quality and exactly as described. Will buy other items from Indigo instruments.
Ian Kelly: I've dealt with Indigo Instruments for years now. They have always been personable and very knowledgeable. Most recently I sent them a hand-drawn sketch of my interpretation of something I saw on YouTube and wanted recommendations on what magnets to use. Chris called me up, discussed the project and made some recommendations. His recommendation was bang on. I couldn't be happier with the end product.
Tracy Myerson: Super fast shipping, excellent prices, and great quality product! I purchased N42 Neodymium magnets, they are the real deal. I had previously bought magnets on Amazon that were advertised as N52, they were just another cheap Chinese fake. These folks sell authentic, high quality stuff and get it to you fast. Highly recommended!
Brenda McIntyre: love these guys, high quality, quick service and reasonable pricing!!
Peter Maran: Been doing business with Indigo for many years. Their Neodymium magnets are superb in quality and price. Other items, tools, magnifiers, tweezers, and so on, all quality made withstanding the test of time.
