The R-1-6 is a great instrument. [I chose EI because of] quality.
Great product at a great price …. (and) reliability.
Great customer service!
This is the second product purchased and I am completely satisfied.
Great service. [I replaced/upgraded] unit in aircraft.
EI tech support is the best.
Great Product, that provides a lot of very helpful engine data in an easy to use and see display! We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive. The CGR-30 had quite a few positive reviews online from other users.
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.
Great service and support for great products!
I have seen your products in other aircraft and have seen their reliability.
Outstanding Customer Service!!
Great product, frees up space
