Logitech G7 Laser Cordless mouse
Most gamers avoid cordless mice with good reason: their battery life can be short-lived, and you run the risk of lag. Logitech addresses both concerns with the G7 laser cordless mouse, which features programmable buttons, adjustable sensitivity levels, and a quick-swappable battery. At $99, it's a good cordless option for the gaming set, but those who don't mind being chained to their computers should consider the, which offers the same level of programmability for $30 less.
The 4.7-ounce G7 is fairly light for a gaming mouse, and most gamers will want more heft; unlike the G5, it lacks customizable weights to give it a heavier feel. Though it looks like it will fit both left- and right-handed users, it's made for righties only. It has two sensitivity buttons conveniently placed below the thumbwheel and another programmable button near the thumb rest. It has a small battery meter on top. An eject button on the bottom lets you quickly swap out the battery. The G7 comes with two battery packs and a USB recharging station. Logitech also includes a wireless receiver that you can plug into your computer's USB port or the USB port on the recharging station.
