The Neksia in our practice has an automated touch screen and more features than our previous edger. So far, it has been very reliable. We had an issue with software on the edger that was resolved quickly with a phone call to tech support. All of the features are easily accessed through the touch screen. The tracer blocker screen is very easy to use to view progressive markings, which speeds up the blocking process. The finished-lens product is reliably accurate and produces a really good shape, size and level.
