Great product, frees up space
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
Works Great!
Easy install, good product. [I chose EI because of my] experience with [the] product.
I have seen your products in other aircraft and have seen their reliability.
E.I. Always Exceeds Expectations!
Your company shares a good reputation!
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.
