Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
Easy install, good product. [I chose EI because of my] experience with [the] product.
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!
No specific instrument
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!
Excellent Service, superb product.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
