Why did you choose our products over the competition? Complete kit and ease of installation.
Easy install, good product. [I chose EI because of my] experience with [the] product.
. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
You folks do a great job. Keep up the good work.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
Sales reps have been very friendly and helpful.
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
Easy Install.
Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.
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.
Original clock failed after MANY years of use. Got the same one as a replacement because original one worked so well.
Great products and very clear install.
