You folks do a great job. Keep up the good work.
Your guys were great at answering all my questions . . . .
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.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
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.
Nice product and good product support!
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
Beautiful graphic display, easy to use, perfect automatic dimming!
