We got the Neksia edger from Essilor Instruments about four years ago, and I must say it is the best purchase I have made. The service from Essilor Instruments has been phenomenal. They have taken care of the instrument, service and training of the staff in the best possible way. Whenever we had a problem, they were always there to help us out.
I would highly recommend the Neksia edger from Essilor Instruments.
