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.

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.

Great product at a great price …. (and) reliability.
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.

Your customer service is excellent and your products are top quality!
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
