Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Easy installation.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
The equipment is fantastic, very intuitive, and easy to use.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
We have other EI products currently and have always been satisfied.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
This is the second product purchased and I am completely satisfied.
