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.
EI tech support is the best.
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
[I chose the CGR-30P because of its] ease of use.
Excellent customer service. Without a doubt the best aviation part I have purchased.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Awesome product. Fast easy installation.
EI’s team is great; you guys are the best.
