Sometimes it's hard to decide which gaming mouse to buy: wired or wireless, ergonomic or compact, more buttons or fewer. The Logitech G604 is certainly one to watch: it combines great features and is $30 off the regular price on eBay.

Logitech released the G604 last year, which uses the company's proprietary "Lightspeed" wireless technology, which not only has remarkably low latency, but also provides a whopping 240 hours of use on a single AA battery. The mouse also supports regular Bluetooth connectivity, so it can be used with devices without USB ports (such as tablets). In this mode, the G604 will last about five and a half months.

Other features include six thumb buttons, customizable macros (once desktop software is installed), Logitech's high-end "Hero" 16K sensor, and a metal scroll wheel. $70 is still a lot for a mouse, but it is a pretty package you're getting.
