Works great!
I have worked with your products before and I like them.
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.
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
The R-1-6 is a great instrument. [I chose EI because of] quality.
Your company shares a good reputation!
Safety and simplicity!
Awesome Product! Great product and fantastic support!
EI shines in providing excellent customer support and its products are reliable, affordable and of high quality.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
