Your (customer) service is excellent!
Love it!
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
I have seen your products in other aircraft and have seen their reliability.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Phone service for ordering was quick and easy. Shipping was quick.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
EI’s products are the only ones we recommend to our customers.
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.
EI tech support is the best.
Easy install, good product. [I chose EI because of my] experience with [the] product.
