After losing all our edging equipment to Hurricane Harvey, we needed a workhorse to get us back up and running. The Delta2 was easy for our opticians to learn to use, and does the finishing for all three locations we have! I would definitely recommend it to others.
Delta2 is a very easy machine to use and extremely convenient for first timers.
Overall Delta2 is a good machine. Had some minor issues with it early on, but Essilor Instruments came out to remedy quickly.
