Your customer support is far superior . . . . I appreciate all your help.
Easy install, good product. [I chose EI because of my] experience with [the] product.
Met all my requirements; great support.
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.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
It works very well; easy operation.
Good equipment at a good price. I have used your products before and have had great success.
Great customer support. My A&P installed a CGR in a Comanche and liked it.
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.
Works great!
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
