Nice product and good product support!
[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.
Sales reps have been very friendly and helpful.
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.
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.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
This is the second product purchased and I am completely satisfied.
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.
EI has the best customer service of any company that I’ve ever dealt with.
