Customer support is great (and the) user interface is superior to other products.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
Works Great! Love it!
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
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.
Haven’t used it yet, but we are excited to & Love the way it looks!!
Nice product and good product support!
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.
Incredible customer service.
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.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
