Great service. [I replaced/upgraded] unit in aircraft.

Adam M. from NSW, Australia
Piper PA-28-181 Cherokee

Easy Install.

Leslie S. from Connecticut
Piper Arrow PA-28R-200

Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.

Nathan V. from Alaska
Cessna 172C

Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.

Larry K. From Kansas
Piper PA-28-181

The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.

Thomas C. from Maine
Maule M-5-235C Luna Rocket

Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.

Art R. From Arizona
Cessna 182P Skylane

The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.

Daniel N. From California
Cessna 175 Skylark

Works Great!

Charlie M. From Texas
American Champion 8KCAB Decathlon

Good to go! Excellent instructions and easy install. Outstanding instrument!

Mark L. from Washington
Cessna 170B

Awesome Tech Support. Like the functions it supports and the fit and look in the panel.

Brian M. from California
Mooney M20F Executive 21

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.

Brewer P. from Mississippi
Beechcraft Bonanza V35B

Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
