Used daily for more than 3 years QWERTY keyboard that is reliable only complaint keys S, D and control begin to fade. The two folding legs are strong, I constantly used for the inclination of this key K300. While being compact 40 x 18 cm I has all the keys that are necessary for me and their positioning is very convenient, and is precisely the F1 key above key 1 & and so on, precisely the F9 key to over well 9C ^. No confusion with a locking indicator "uppercase" and keypad lock that is visibly placed at the top right. On the other hand the keys are not backlit. Dimensions 40 cm x 18 cm. weight: 580 gr.
