Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.

This is the second product purchased and I am completely satisfied.

I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.

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.

Sales reps have been very friendly and helpful.
Good to go! Excellent instructions and easy install. Outstanding instrument!
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Looks great. Works great.

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.
