Good to go! Excellent instructions and easy install. Outstanding instrument!

Mark L. from Washington
Cessna 170B

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.

Todd M. from Ohio
Cessna 195

[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.

Dom M. from Australia
Van’s Aircraft RV-6

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.

The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.

Thomas C. from Maine

Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.

Zarick J. from Florida

All looks very nice. [I chose E.I. because of] previous experience.

Filip G. from Torslanda, Sweden
Van’s Aircraft RV-6

I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

Anthony H. from Oregon
Piper PA-18 Super Cub

Good equipment at a good price. I have used your products before and have had great success.

Ryan M. from Oregon

Ben C. from Alaska
Piper PA-22-160

This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!

Charles M. from South Dakota
Cessna 150F

Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
