Customer Testimonials

This is the second product purchased and I am completely satisfied.

K. Mallette from Mississippi
C170B

. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.

Adriano S. from Australia
RV6A

Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.

Nathan V. from Alaska
Cessna 172C

Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.

Phillip B. from Oklahoma
Cessna 210N Centurion / Turbo Centurion

[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.

Dom M. from Australia
Van’s Aircraft RV-6

[I chose EI because they offer a] certified replacement vs. back-up only and they look great.

Nic C. from South Carolina
Piper PA-28 Cherokee

Great Product, that provides a lot of very helpful engine data in an easy to use and see display!  We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive.  The CGR-30 had quite a few positive reviews online from other users.

Ryan O. from North Dakota
Cessna 182D

I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.

David M. From South Carolina
Cessna 182J Skylane

After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!

C Scott Van W. From Idaho
Cessna 175 Skylark

I have seen your products in other aircraft and have seen their reliability.

Juan P. from British Columbia, Canada

Great tech support. Someone always answers and gives accurate concise information.
