You folks do a great job. Keep up the good work.
I really enjoy your products [because they are] simple and easy to use and affordable.
Your customer support is far superior . . . . I appreciate all your help.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Gauge works great! Very happy with purchase.
All looks very nice. [I chose E.I. because of] previous experience.
Excellent Service, superb product.
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.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
The R-1-6 is a great instrument. [I chose EI because of] quality.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
