It is compact and its touchpad is large enough to benefit from comfort.
Regarding quality by cons, we could expect more from Logitech. It is a key to low-end plastic, very light, it does not really exudes quality. Certainly at that price, you should not expect the quality of a mechanical keyboard like Cherry, but the keyboard "chiclet" the K400 could have been better. Especially by watching the keys surfaces, we see some "dance", their alignment is not properly calibrated.
In short, a keyboard that would win 2 more stars if plastics were revised upward and the quality of pressing keys also.
