Customer Testimonials

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.

Mike D. From B.C. Canada
Cessna 210B

Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.

Dale C. from Ohio
Cessna 182D Skylane

Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, 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.

Phillip B. from Oklahoma
Cessna 210N Centurion / Turbo Centurion

Outstanding Customer Service!!

Rocky C. From Texas

Safety and simplicity!

Andrew L. from Florida
Piper PA-28-235 Cherokee Pathfinder

Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.

Art R. From Arizona

Good to go! Excellent instructions and easy install. Outstanding instrument!

Mark L. from Washington

[I chose EI because they offer a] certified replacement vs. back-up only and they look great.

Nic C. from South Carolina
Piper PA-28 Cherokee

Customer Service is far superior… with an excellent record of resolving … technical issues.

C.J. R. from North Carolina
Mooney M20C Ranger

I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.

Nicholas A. From Ohio
Piper PA-32R-300

[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
