Logitech MX518 Optical Gaming Mouse Repair

I'm at it again and this time, I fixed the mouse buttons on the Logitech MX518 Optical Gaming Mouse. I had a problem with this one in that the left mouse button wasn't mounted all the way down and when I desoldered the left mouse button, one mount came completely off and another one was on it's way off, but I soldered everything back on and it worked just fine. I used the same Omron D2F-T that I used to repair the Logitech V550 Nano Cordless Laser Mouse. The 3rd mouse button below the left mouse button is for the wheel. That particular button doesn't get used much so I didn't replace that one. Again the new mouse buttons are stiffer than the original clicky mouse buttons.
