Love this keyboard. Slim and doesn't take up much room on my desk. The sound of the mouse clicks are almost non-existent. Keyboard chiclet keys are well spaced out and make typing fast. Not noisy, so great for shared office spaces or uni library. No lag with both mouse and keyboard. Wouldn't recommend it for gaming, but excellent for school and office work. Mouse is not ergonomic but good size for transporting around in office or school bag.
