[Customer service] is great!
Incredible customer service.
The reviews online were very good. Customer service has been great.
The equipment is fantastic, very intuitive, and easy to use.
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.
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Looks great. Works great.
Outstanding Customer Service!!
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
