Input: Consider Input: Trackball feels as though its running with occasional grains of sand. Esc Key needed to \"get things going\" on first use. Key 7 fell out and seems to be partially broken as it won't clip back in as securely as the other keys. Rubber trim and foot fell off. This keyboard is slowly coming apart

Output: Negative Review
