Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
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.
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.
People [at EI] were great to work with.
Good engineering support.
Awesome Product! Great product and fantastic support!
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
Your customer support is far superior . . . . I appreciate all your help.
Love it!
I have worked with your products before and I like them.
EI tech support is the best.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
