Love it!

Corey B. From Texas
Grumman American AA-5A Cheetah

I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.

Nice unit. EI is the best!

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.

Your customer support is far superior . . . . I appreciate all your help.

Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.

The CGR-30P is working great and it’s an outstanding addition to our avionics package.

Charles J. from Idaho
PA-28-181

Great Product, that provides a lot of very helpful engine data in an easy to use and see display!  We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive.  The CGR-30 had quite a few positive reviews online from other users.

Ryan O. from North Dakota

We’ve worked with EI for years and love the product and support always received. Quality & dependability.

My mechanic said that your product was very good, and he was correct.
