Good engineering support.
EI has the best customer service of any company that I’ve ever dealt with.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
Beautiful graphic display, easy to use, perfect automatic dimming!
Outstanding Customer Service!!
We liked the price and the reputation of your company.
Your sales and support teams are very helpful.
[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.
People [at EI] were great to work with.
Excellent installation instructions [&] recommend[ed] by others.
