Easy install, good product. [I chose EI because of my] experience with [the] product.
Works Great!
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.
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
Very easy to install and directions were straight-forward.
Good product; company is eager & willing to help
Great customer support. My A&P installed a CGR in a Comanche and liked it.
Pleasure supporting folks with like values.
Best sales team.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
EI’s products are the only ones we recommend to our customers.
