Great product. [I chose EI because] you have no competition.
[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.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
It works very well; easy operation.
Nice bright display.
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.
Great product, frees up space
We have other EI products currently and have always been satisfied.
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
Works Great! Love it!
