Purchasing Mr. Blue was a great experience from the beginning, in 2011. Our Essilor Instruments sales rep has been a great resource on what equipment fits our office needs. In the last seven years, we have been able to increase productivity by keeping drill, high base curve, and custom bevel jobs in-house. This keeps turn-around time at a minimum and keeps more profits in the office. Technical support is always timely in getting information I need. Great instrument for our practice now and for the future.
