Like the G703 and G903, this means every G502 Lightspeed ships with a placeholder, a circular plastic disc that slots into the bottom and is held magnetically.

The Logitech G502 Lightspeed is Powerplay compatible though (more on that later), meaning the underside needed to be redesigned around the circular Powercore charging module. Since its initial release, the G502’s underside has featured a large removable panel that allowed the user to insert up to five 3.6 gram weights, either to make the mouse heavier overall or to skew the weight distribution to one side. Most of the noteworthy changes have been made to the bottom of the Logitech G502 Lightspeed though. The more fastidious among you might notice the G502 Lightspeed trades out solid metal for the spoked wheel already in use on the Logitech G903, cutting down on weight without reducing actual performance-though I admittedly find the soft-touch rubber coating less distinctive than the raw metal of the G502 Hero. The G502’s traditionally used a solid metal scroll wheel, a fairly heavy piece of hardware. There have been slight changes, of course.
