I used the Ouroboros before, gave up and looked for an alternative mouse after just a few months. The ergonomics on the mouse simply sucks, really uncomfortable and the tracking is weak, battery life even weaker.

Personally I'm using the G602 for my laptop and workplace, and the Mionix Naos 7000 at home. Both are excellent mice. If you have no use for the wireless capabilities, the G602 will just be heavier for no reason (unless you like that). The Mionix is EXTREMELY HARD to find in Malaysia though.

I recommend the G402 or G502 from Logitech, excellent sensor and tracking. Shape also should be comfortable for most people, just not for me.

The Roccat Kone Optical, Steelseries Rival, Razer Deathadder, Corsair M45 are also all excellent choices for wired mice.
