"A delightful company to work with. Could not have done it without your expertise."

"EI excels in responsiveness, support and flexibility. I very much appreciate EI’s ability to adapt on the fly."

"I appreciate the work EI does most of all because it makes my job easier."

"Overall, EI does a great job in dealing with everything we throw at them. They are responsive and understanding of us, even though it may not always be the most reasonable of requests. As a buyer, I feel lucky to have a supplier that works with us like they do."

"Working on a project that had a board that was simply not manufacturable the way it was set up, EI went above and beyond to help with engineering and still met a very short deadline."
