Works Great!
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
Pleasure supporting folks with like values.
[I chose the CGR-30P because of its] ease of use.
Your products always work great! Great customer service and a quality product that we have used for years.
Excellent tech help…
The reviews online were very good. Customer service has been great.
Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.
I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
[I chose EI because of its] Reputation and value.
