I just got the LX7, wireless, it's the same shape/size as that one, but has two extra buttons below the scroll wheel. If it's like mine, the scroll wheel clicks down, plus left and right tilt clicks. I like the feel and sensitivity of the buttons except the wheel down click is so tough that many times I did a left or right tilt click instead, so I just don't use that one, but I still have one more than I expected when I bought it. They advertise as a 5 button but with the scroll wheel tilt clicks it's 7.<br><br>Regular click of course, one click is Command-click to open links in a new tab, one gives me Expose, one gives a Command-W, one a Control-click, one is Mute.<br><br>The Scrolling and Pointer speed have good controls.<br><br>------>#1 - JD's Trivia game<br><br>------>#2 - MM-MCF Trivia game
