Purchased in white and red. In red letters printing has not taken 3 months! The main keyboard letters, quickly disappeared, curious that the impression was made and not hitting side side glue! A useful product but very disappointing, zero quality printing even if the cutting and glue are correct. Finally, besides the red is not strong enough to stand properly on the black, the placement of certain characters is not happy on a qwerty keyboard Logitech. In white, nothing to say, the holding time is much better.
