Customer support is great (and the) user interface is superior to other products.
Pleasure supporting folks with like values.
Electronics International supports their products. Rare repairs are done quickly.
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.
Great product, frees up space
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
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.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
EI shines in providing excellent customer support and its products are reliable, affordable and of high quality.
The layout and quality is impressive.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
