Haven’t used it yet, but we are excited to & Love the way it looks!!
Your (customer) service is excellent!
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
Customer Service is far superior… with an excellent record of resolving … technical issues.
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.
I really enjoy your products [because they are] simple and easy to use and affordable.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
Keep it up. I’ll keep coming back.
Safety and simplicity!
