The wireless mouse ships with an RF base station, which doubles as a battery charger. Battery life is phenomenal; you can go days without recharging. We particularly like the battery-power meter along the top of the mouse. You may forget to recharge the MX1000 at the end of the day because the battery lasts so long on a single charge, so the three green LEDs are a good reminder: when it gets down to one light, it's time to recharge.
Despite the fact that the MX1000 uses a compact lithium-ion battery, it's still on the large and heavy side for a mouse. Its size may not appeal to everyone, but we preferred the substantial feel to that of a mouse that seems like a piece of cheap plastic.
The Logitech MX1000 Laser Cordless Mouse is the one mouse that truly has it all: precise control, ergonomic comfort, cordless freedom, and long battery life, plus an attractive overall look to boot.
