Easy to read keyboard, processing improvement

The keyboard is very readable, far better than some illuminated keyboard. Functional properly. Unfortunately, the labeling is only "painted", so that when used intensively after 2weeks a clearly visible wear occurs. Letter E now lacks the means line, A, R, N and S are already corroded. This leads to significant point deduction. Otherwise, the idea with yellow buttons and black font for people with certain visual impairments is a great way to recognize the keyboard better.
