Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Very pleased with the quality. [Chose because of] positive reviews from other aircraft owners.
Works great, super install.
I have other EI products and your support is great.
Awesome Product! Great product and fantastic support!
This is the second product purchased and I am completely satisfied.
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
My mechanic said that your product was very good, and he was correct.
Excellent customer service. Without a doubt the best aviation part I have purchased.
Your products always work great! Great customer service and a quality product that we have used for years.
Nice bright display.
After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
