Have decided after a long search for this unit to see me no sparkle. Use two identical screens for processing with a CAD program - almost no text here. For this he is excellent. A little complicated is the subsequent rotation by 90 degrees. But once it is set changes nothing. Helpful and Eye Care is the black version. Have worked with white screens, subjectively it is tiring. Important in considering the double purchase: rather longer think and then two at the same time order because even minimal changes in color of the plastic rim when standing side by side in the long bones have a disruptive effect. The adjustability in height could be more, otherwise a solid device.
