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.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Great product, frees up space
Great service. [I replaced/upgraded] unit in aircraft.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
I have seen your products in other aircraft and have seen their reliability.
Works Great! Love it!
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.
You folks do a great job. Keep up the good work.
Straight up install no issues. Works as advertised!
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
