Easy Install.
Pleasure supporting folks with like values.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
Very impressed with the clarity and readability of the CGR-30P gauge.
My mechanic said that your product was very good, and he was correct.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
You folks do a great job. Keep up the good work.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Sharp-looking gauges. [I chose EI because of your] reputation.
Excellent Service. Superb Product.
