We’ve worked with EI for years and love the product and support always received. Quality & dependability.
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.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Very nice product, giving a real advantage on fuel management.
Installation went great. The Fuel Flow is dead on.
This is the second product purchased and I am completely satisfied.
Your customer support is far superior . . . . I appreciate all your help.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
EI tech support is the best.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Customer Service is far superior… with an excellent record of resolving … technical issues.
