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.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Straight up install no issues. Works as advertised!
I have never had an issue with any EI products… it looks fantastic on the panel.
Nice bright display.
My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
Pleasure supporting folks with like values.
MVP-50 is a really great product
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
