Looks great. Works great.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
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.
EI tech support is the best.
Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Great… price [&] support
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
[Customer service] is great!
Great tech support. Someone always answers and gives accurate concise information.
