It works very well; easy operation.
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
My mechanic said that your product was very good, and he was correct.
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
The equipment is fantastic, very intuitive, and easy to use.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
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.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
Pleasure supporting folks with like values.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
