Great service. [I replaced/upgraded] unit in aircraft.
Great product. So easy to read compared to the originals.
The tach looks and operates amazing. Extremely accurate.
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.
Haven’t used it yet, but we are excited to & Love the way it looks!!
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.
Gauge works great! Very happy with purchase.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Very happy with our new tachometer!
