Nice product and good product support!
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Sharp-looking gauges. [I chose EI because of your] reputation.
My mechanic said that your product was very good, and he was correct.
MVP-50 is a really great product
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.
Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Your company shares a good reputation!
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
Excellent tech help…
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
