Your products always work great! Great customer service and a quality product that we have used for years.
EI shines in providing excellent customer support and its products are reliable, affordable and of high quality.
Met all my requirements; great support.
I have never had an issue with any EI products… it looks fantastic on the panel.
Excellent customer service. Without a doubt the best aviation part I have purchased.
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.
Responsive customer service, kudos to [customer service].
Great product. So easy to read compared to the originals.
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.
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
