The R-1-6 is a great instrument. [I chose EI because of] quality.
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 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.
Love it!

Good equipment at a good price. I have used your products before and have had great success.
