Very impressed with the clarity and readability of the CGR-30P gauge.
We liked the price and the reputation of your company.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
Your company shares a good reputation!
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.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
Good product; company is eager & willing to help
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
Easy install, good product. [I chose EI because of my] experience with [the] product.
