Good equipment at a good price. I have used your products before and have had great success.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
I have seen your products in other aircraft and have seen their reliability.
You folks do a great job. Keep up the good work.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
We have other EI products currently and have always been satisfied.
Fantastic customer support!
Nice unit. EI is the best!
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.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Simple and Easy.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
