Query: Won't connect, Flimsy tilt, Short battery life

Don't get this product! I returned one already.1. Won't connectMouse didn't work out box. Had to return to get another one. What a hassle. I wonder how long this mouse will last.2. Flimsy tiltWhat a lousy and flimsy design... How often does one use side scroll anyway? In any case, to use it takes large amount of finger extension and force. Lousy gimmick at best. And I miss the scroll with "click" as smooth scroll doesn't feel "right".3. 6 month battery life?Now that's a LIE! The damn Intellipoint software keeps on reminding me after 2 months that I need to change the battery and I used it only at home. I wish I got the Logi with built-in charger.Finally, I wish I bought the Logi with 600 dpi and recharger instead. I tried one and regret this terrible unreliable piece of trash.
