Works great!
You folks do a great job. Keep up the good work.
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.
Good engineering support.
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
I have never had an issue with any EI products… it looks fantastic on the panel.
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.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
Great product at a great price …. (and) reliability.
Great product. So easy to read compared to the originals.
Installation went great. The Fuel Flow is dead on.
