Sigh, another potentially good mouse ruined by utterly inexcusable schoolboy errors.
I'm using this cheap wireless mobile mouse today, a Microsoft WMO 3500. It's just a simple 3-button mouse with an AA battery for power and nothing fancy like bluetooth, just your old 2.4G RF transceiver.
However, looking at both the description and video on page four, I can see that one of the most critical buttons a gaming mouse can have (mouse 3) is a total disaster. This Microsoft mouse isn't a gaming mouse, but the scroll wheel clicks as you'd expect it to: No noticeable pre-travel and the actuation force required to click it isn't too different to mouse 1 and mouse 2. It really isn't hard to make a decent scroll wheel that is both a good wheel and a good button. Plenty of cheap, unexciting office mice have perfected this simple feat to the point that I don't even notice the scrollwheel on them. They just work.
Since scrolling and clicking are on the same button and the click action is often for an option in the scrollable menu (whether it's a menu or weapon/item select, the expectation is the same) having a scrollwheel that can click without accidentally scrolling or scroll without accidentally clicking is right up there near the top of the priorities list for a gaming mouse. In fact, I think it's joint second with latency after a decent, linear sensor.
