The R-1-6 is a great instrument. [I chose EI because of] quality.
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.
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
We liked the price and the reputation of your company.
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!
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Works great!
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.
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Very impressed with the clarity and readability of the CGR-30P gauge.
