Mr. Orange has changed the way we do business!! This is the second edger from Essilor in my 35-year-old office. We have had it for the past 5 years without an ounce of trouble. It really does what it says it does. Every lens is edged to perfection….most times inserted without heating the zyl frame. If there is an occasional question or problem, our Essilor Instruments sales rep is a phone call away and we have our answer immediately. I highly recommend this product to any office that needs to make a change in the way they finish lenses…..from edge to polish to drilling holes…It far surpasses my expectation.
