Customer Service is far superior… with an excellent record of resolving … technical issues.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
You folks do a great job. Keep up the good work.
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.
Great product, frees up space
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
People [at EI] were great to work with.
Good to go! Excellent instructions and easy install. Outstanding instrument!
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.
Looks great. Works great.
Easy installation.
