The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.

Charles M. from South Dakota
Cessna 150F

Great product. So easy to read compared to the originals.

Don M. From Texas
Cessna 182Q Skylane

Great Service.

Flying Academy from New York
Piper PA-28-161 Warrior

Great product. [I chose EI because] you have no competition.

Barry B. from Louisiana
Thrush Aircraft

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!

C Scott Van W. From Idaho
Cessna 175 Skylark

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.

Casey R. from Oklahoma
Cessna 172M

I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!

Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
