I really enjoy your products [because they are] simple and easy to use and affordable.
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.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
You folks do a great job. Keep up the good work.
[Customer service] is great!
Great product, frees up space
People [at EI] were great to work with.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
Your customer service is excellent and your products are top quality!
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
