Great service and support for great products!
I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
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!
Installation went great. The Fuel Flow is dead on.
