This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Simple and Easy.

Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
Easy install, good product. [I chose EI because of my] experience with [the] product.

My mechanic said that your product was very good, and he was correct.
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
I have never had an issue with any EI products… it looks fantastic on the panel.
