Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
Nice bright display.
Gauge works great! Very happy with purchase.
Met all my requirements; great support.
Easy Install.
[Customer service] is great!
Great product. So easy to read compared to the originals.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Love it!
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
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.
