In terms of comfort, the Logitech G600 is a delight for anyone with a palm grip. Since the thumb controls 12 of its 20 buttons, there is no groove for the thumb. Rather, the index finger controls the left button, the middle finger controls the right button and the ring finger rests on a third button that activates the mouse’s macro controls.
At 4.69 ounces (133 grams), the G600 is a bit heavier than the standard gaming mouse, and at 4.6 x 2.9 x 1.6 inches (118 x 75 x 41 mm), it’s quite a bit bulkier, too. However, the heft makes the mouse feel substantial and satisfying to use.
