Normal click sound, but overall a pretty useless keyboard and mouse combination. For years I have used the large-format Microsoft wireless keyboard and mouse. But, QWERTY is hard to find in Switzerland, so recently I decided to try Logitech (available here in QWERTY). Big disapointment. My typing is slower, more cumbersome and has more errors than before because egonomically Logitech doesn't get it. And, the mouse is nowhere near as comfortable as the wireless large-format one from Microsoft. I'll be buying Microsoft keyboard and mouse on my next trip outside Switzerland where QWERTY is available, and dump this Logitech stuff.

Scrolling is very silent and smooth. Clicking is normal I would say. Haven’t used B220 so cant really compare, but overall I’m happy with the purchase.
