While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!

Jeffrey S. From Missouri
Cessna 170N

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.

We’ve worked with EI for years and love the product and support always received. Quality & dependability.

Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.

Dale C. from Ohio

Good equipment at a good price. I have used your products before and have had great success.

Ryan M. from Oregon

Straight up install no issues. Works as advertised!

John L. from Georgia
Piper PA-28-151 Cherokee Warrior

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 have never had an issue with any EI products… it looks fantastic on the panel.

Thomas A. from Oklahoma
