Love it!
Excellent tech help…
Your products always work great! Great customer service and a quality product that we have used for years.
Your customer service is excellent and your products are top quality!
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
Great product, frees up space
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.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
Very impressed with the clarity and readability of the CGR-30P gauge.
Straight up install no issues. Works as advertised!
