Great tech support. Someone always answers and gives accurate concise information.
Your customer service is excellent and your products are top quality!
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.
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Looks great. Works great.
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
Your products always work great! Great customer service and a quality product that we have used for years.
Simple and Easy.
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.
Great product. [nothing else] can compete.
