We have always had Essilor equipment. When we were ready to buy a new machine three years ago, I thought I would stay with the same company because I always liked working with Essilor and the Kappa K that we had was a great workhorse. I did look at other machines but thought Mr. Orange would be a good fit. It was very easy to learn for both experienced opticians and those who had never edged before. We are now using it to make Chemistrie clips in-house. I use the Essibox also and the Mr. Blue tracer is great.
