The R-1-6 is a great instrument. [I chose EI because of] quality.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
Big improvement over old cluster (gauges). Good customer service.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.
Love it!
 Fantastic customer support!
