Big improvement over old cluster (gauges). Good customer service.
Customer support is great (and the) user interface is superior to other products.
We chose your product because of the great support and reputation your company sustains.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Great product. [I chose EI because] you have no competition.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
Tach fits my panel nicely, was easy to install.
Phone service for ordering was quick and easy. Shipping was quick.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
Incredible customer service.
Great service and support for great products!
