I like how the kits ship with everything needed for install and the wire labeling was very helpful.

Great product at a great price …. (and) reliability.
Excellent tech help…
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
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.
