Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
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.
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.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
Awesome Product! Great product and fantastic support!
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
Good to go! Excellent instructions and easy install. Outstanding instrument!
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!
This is the second product purchased and I am completely satisfied.
Your customer support is far superior . . . . I appreciate all your help.
Haven’t used it yet, but we are excited to & Love the way it looks!!
Great service. [I replaced/upgraded] unit in aircraft.
