Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.

All looks very nice. [I chose E.I. because of] previous experience.

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.
