Good equipment at a good price. I have used your products before and have had great success.
Love it!
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
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.
People [at EI] were great to work with.
Your customer service is excellent and your products are top quality!
Awesome product. Fast easy installation.
Keep it up. I’ll keep coming back.
[I chose EI because of its] Reputation and value.
All looks very nice. [I chose E.I. because of] previous experience.
Excellent Service, superb product.
E.I. Always Exceeds Expectations!
