Phone service for ordering was quick and easy. Shipping was quick.
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
