Easy install, good product. [I chose EI because of my] experience with [the] product.
Very nice product, giving a real advantage on fuel management.
Nice bright display.
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.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
Great service. [I replaced/upgraded] unit in aircraft.
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Your customer service is excellent and your products are top quality!
Easy Install.
