Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Fantastic customer support!
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!
Met all my requirements; great support.
I have worked with your products before and I like them.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
Haven’t used it yet, but we are excited to & Love the way it looks!!
Sales reps have been very friendly and helpful.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
