When Logitech announced their new line of gaming mice I was a little surprised to see that one of them was going to be a wireless mouse. I’ve always been a big fan of their gaming mice (I’ve had a MX510 since the day they hit the stores) but I was a little wary of a wireless mouse as there is usually a bit of lag associated with wireless controllers. This perception was re-enforced when I reviewed Logitech’s Cordless Desktop MX 3000 Laser a few weeks back and found that the wireless mouse included with that exhibited some lag when playing games like Battlefield 2 and CounterStrike:Source. I’m happy to say that somehow Logitech has managed to deliver a wireless mouse that shows no perceptual lag when gaming with the G7 gaming mouse.

The G7 and its corded twin the G5 share the same five button design which has a form factor that will be familiar to those who have used Logitech’s MX500 series of mice. The G7 inherits the same overall shape of the previous mice but loses a few of the buttons. Gone is the forward button on the side of the mouse, the two scrolling buttons above and below the scrolling wheel, and the application switching button that sat below the wheel. Logitech did add two buttons below the wheel which allow you to increase and decrease the resolution of the mouse. The scroll wheel also now supports side scrolling (something I’ve yet to find a use for). While I don’t miss the scrolling buttons I really did miss the forward button. I’m sure I’m in the minority on this one but it was kind of a helpful button to have around.

Inside the box you find the silver and green mouse, two LI-ion batteries, a USB recharging unit with USB port, the USB wireless receiver, and a CD with Logitech’s Set Point software. The green is a nice hunter green metallic that contrasts nicely with the sea of grey and black items that make up my PC rig. Besides the difference in buttons the G7 has two other notable differences from the other Logitech mice I’ve used. The first is the dual purpose indicator on the bottom left part of the mouse. The display shows the currently selected resolution of the mouse as well as the amount of juice left in the mouse. The resolution is displayed in orange while you are using the mouse and then it switches over to a green display when you stop using the mouse. The Setpoint software will also notify you when the battery is low by popping up a warning message.

The second major difference in the G7 is the three large Polytetrafluoroethylene (PTFE) feet on the bottom o...
