EI has the best customer service of any company that I’ve ever dealt with.
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.
Great service and support for great products!
Customer Service is far superior… with an excellent record of resolving … technical issues.
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!
Compact, precise, awesome!
Sharp-looking gauges. [I chose EI because of your] reputation.
The reviews online were very good. Customer service has been great.
[I chose EI because of its] Reputation and value.
Good equipment at a good price. I have used your products before and have had great success.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
