All looks very nice. [I chose E.I. because of] previous experience.
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
Your customer support is far superior . . . . I appreciate all your help.
Easy install, good product. [I chose EI because of my] experience with [the] product.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Awesome Product! Great product and fantastic support!
. . . looks really good! Friends have these installed and give very good reviews.
Outstanding Customer Service!!
Great product and excellent customer service!
Keep it up. I’ll keep coming back.
Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
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.
