I have never had an issue with any EI products… it looks fantastic on the panel.
EI has the best customer service of any company that I’ve ever dealt with.
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.
Responsive customer service, kudos to [customer service].
Pleasure supporting folks with like values.
Very easy to install and directions were straight-forward.
The layout and quality is impressive.
We chose your product because of the great support and reputation your company sustains.
Great… price [&] support
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
The equipment is fantastic, very intuitive, and easy to use.
Customer Service is far superior… with an excellent record of resolving … technical issues.
