Excellent tech help…
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
People [at EI] were great to work with.
While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!
[Customer service] is great!
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
The CGR-30P is a fantastic product and EI has excellent customer service. EI is the leader in engine monitors with a strong track record.
