I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

Your company shares a good reputation!
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
[I chose the CGR-30P because of its] ease of use.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Awesome product. Fast easy installation.
Works great!
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
We liked the price and the reputation of your company.
