What our customers say

  • "I would like to express our appreciation for your efforts in making this a successful project for us, especially to George for his expertise in refining the design and to your production for executing flawlessly. We achieved very high levels of consistency in our build, at least in part due to the very consistent performance of the magnetics."

    - Nick V., Geo Spectrum

  • "We solicited a new transformer design from E Craftsmen when a competitor of theirs was unwilling to improve on an underperforming product for us. The design proved perfect for the application resulting in many hundreds of flawless units being deployed in transit vehicles throughout the world. Thank you E Craftsmen for one thing we never have to worry about."

    - Jim, Trak Com Wireless Inc.

  • "Great on all counts. We had no issues with Electronic Craftsmen and would recommend them to anyone looking for products of your specialty. We consider you a strategic resource when it comes to small magnetics, and will continue to take advantage of your services as required."
