Love my new engine monitoring system.
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.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
Great product at a great price …. (and) reliability.
Great product. So easy to read compared to the originals.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
Fantastic customer support!
The reviews online were very good. Customer service has been great.
People [at EI] were great to work with.
I have worked with your products before and I like them.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
