The equipment is fantastic, very intuitive, and easy to use.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Gauge works great! Very happy with purchase.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
E.I. Always Exceeds Expectations!
Great product. So easy to read compared to the originals.
Incredible customer service.
You folks do a great job. Keep up the good work.
I really enjoy your products [because they are] simple and easy to use and affordable.
