Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Great product, frees up space
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Nice product and good product support!
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
You folks do a great job. Keep up the good work.
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
Great product. [I chose EI because] you have no competition.
I have several EI units in my aircraft and have been very pleased with their reliability over the years. The other great part, besides the unit themselves, is the support from you all. Thank you for your support over the years… I chose IE for your reputation for quality and pricing. I have been very pleased with my units. My graphic engine analyzer, fuel flow meter, volt/amp meter, RPM and now Manifold gauge.
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
