I have seen your products in other aircraft and have seen their reliability.
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.
Straight up install no issues. Works as advertised!
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
Excellent Service, superb product.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
EI’s team is great; you guys are the best.
Your sales and support teams are very helpful.
