Looks great. Works great.
Very happy with our new tachometer!
The tach looks and operates amazing. Extremely accurate.
Your customer service is excellent and your products are top quality!
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.
My mechanic said that your product was very good, and he was correct.
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.
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.
Your (customer) service is excellent!
Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
