Then pop the batteries into the mouse, choose Hi or Lo, and Bob’s your uncle. To set it up, stick the USB dongle into the USB extender, and plug the extender into your PC. With one AA battery, the weight jumps to a still-svelte 112.3g, and with both batteries loaded up, you’re looking at 135.7g, which is pushing the limits for what will feel comfortable to an average user. Empty (that is, without batteries), it’s a flyweight at just 88.9g. The weight of the G603 fluctuates widely depending on the battery situation. The switches underneath are made by Omron. Logitech stated that the left and right buttons have no pretravel, which it noted was especially hard to create with the removable magnetic top cover design. On the underside of the mouse is the switch to select Hi, Lo, or off, as well as a Lightspeed/Bluetooth button.

Although you program buttons and configure the mouse settings within LGS, you can save the profiles to the G603’s internal storage as opposed to saving to the PC. There are six physical buttons (left and right click, forward and back buttons on the left side, DPI button, and clickwheel), and all of them are programmable.

The G603 is programmable via the Logitech Gaming Software (LGS). You can easily access the battery chamber via a magnetically attached top panel. It’s also a de facto method of altering the weight. One nifty feature is that you can pop out one of the two batteries and keep the mouse running.
