[I chose the CGR-30P because of its] ease of use.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
Great product. So easy to read compared to the originals.
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
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!
I have never had an issue with any EI products… it looks fantastic on the panel.
All looks very nice. [I chose E.I. because of] previous experience.
Great product and excellent customer service!
Big improvement over old cluster (gauges). Good customer service.
Great service. [I replaced/upgraded] unit in aircraft.
EI’s products are the only ones we recommend to our customers.
