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.
Nice unit. EI is the best!
Great… price [&] support
All looks very nice. [I chose E.I. because of] previous experience.
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
The R-1-6 is a great instrument. [I chose EI because of] quality.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.
