Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
Great Service.
All looks very nice. [I chose E.I. because of] previous experience.
Great service and support for great products!
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.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Compact, precise, awesome!
Great tech support. Someone always answers and gives accurate concise information.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
