Logitech G7 Cordless Laser Mouse

This mouse has the same specs as the Logitech G5; the difference is the fact that it is wireless. This means you need to recharge it fairly frequently depending on your usage, although Logitech have cleverly provided twin swappable batteries so you can be recharging one while you play with the other. It can be used from several metres away, although that doesn’t seem very useful. It is also slightly more expensive than the G5 and despite claims to the contrary there is always some lag with cordless mice.
