Clicking the wheel turns on / off the ratchet in the wheel. There is no middle button. Absolutely not. Logitech, are you okay with your head at all? Mouse without middle button? Seriously? You can reassign an additional button to a click, but this is not convenient and slows down the work (because you have to move your finger from the wheel to the button and vice versa), or assign it to the side pressing of the wheel (which is also very inconvenient, but at least something). I don't recommend this piece of engineering.
