Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
Great Service.
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
Nice product and fulfills the requirement.
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.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
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.
All looks very nice. [I chose E.I. because of] previous experience.
Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Works great!
Great product. So easy to read compared to the originals.
