Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!

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.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
Sharp-looking gauges. [I chose EI because of your] reputation.
