Yet another addition to Logitech?s line of wireless notebook mice is the V200, which is a predecessor to the V500 ? a superior product in general. The V200 comes at a significantly lower price tag than its successor, but with that you are also sacrificing a refined ergonomic design, though you get excellent performance for general applications. The V200 has about a yearlong battery life with a 2.4GHz of frequency for the wireless technology.
