After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.

My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
Works great!
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.
Safety and simplicity!

Your company shares a good reputation!
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!
