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.

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.

The reviews online were very good. Customer service has been great.
My mechanic said that your product was very good, and he was correct.
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
