Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.

William F. from Maryland
Mooney M20C Ranger

Gauge works great! Very happy with purchase.

Aryan M. from California
American Champion 8KCAB

I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

Anthony H. from Oregon
Piper PA-18 Super Cub

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

Juan P. from British Columbia, Canada

Love it!

Corey B. From Texas
Grumman American AA-5A Cheetah

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

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.

Justin R. from Texas
Cessna T207A Turbo Skywagon

This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!

Karl P. from Maine

Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.

Doug F. from Nevada

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

Great service for Electronics International.  Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.
