Great… price [&] support
The R-1-6 is a great instrument. [I chose EI because of] quality.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
Good equipment at a good price. I have used your products before and have had great success.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Great Product, that provides a lot of very helpful engine data in an easy to use and see display! We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive. The CGR-30 had quite a few positive reviews online from other users.
I really enjoy your products [because they are] simple and easy to use and affordable.
Looks great. Works great.
Excellent Service. Superb Product.
Awesome Product! Great product and fantastic support!
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
Excellent installation instructions [&] recommend[ed] by others.
