Well documented installation process and Support was helpful.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.
