So bear that in mind if you're all about aesthetics.

(The DPI monitor on the side lights up, too, but it's so small you'll hardly notice it.) While RGB features have never been the primary reason to buy or avoid a mouse, this one is going to look plain black most of the time. While you can indeed program the color of the G logo on the palm rest, that's just about the only part of the mouse that lights up. (The sniper button is a good choice for this, in my experience, although I didn't use it too much in general.) You'll have access to these whenever you hold down a button of your choice. The software is pretty straightforward, and you can even program a secondary set of commands known as G-Shift. The G502 Lightspeed runs on the Logitech G Hub software, which lets users customize DPI (100-16,000), control backlighting and program all of the mouse's buttons. Once I finished testing the G502, I went right back to the G903, and I haven't looked back. The G502's design still holds up extremely well, but for the same price, Logitech's other high-end wireless mice may feel a bit better to hold. Compared to the angular, bulky G502, both newer mice seem positively futuristic, with sleek curves and, in the G903's case, swappable parts to offer complete ambidexterity. But since 2014, Logitech has launched two fantastic high-end wireless mice series: the Logitech G900 (currently the G903) and the Logitech G Pro Wireless, both of which also retail for $150 by default. The design hasn't changed at all in five years, which is admirable in a way. I do, however, have one small criticism of the G502's design - which may actually be a point in the device's favor. MORE: Our Favorite Gaming Mice for Every Genre It's a pain that you can't use the 4-gram weights and the PowerPlay attachment simultaneously, but this is an annoyance not a deal breaker. Adding and removing weights is much easier than before, and there's still a little carrying case to store extra weights. I actually prefer the G502 Lightspeed's approach to weights this mouse uses small, trapezoidal weights rather than the previous model's convoluted, semi-hexagonal models. The design isn't exactly the same as on the older mouse, since the G502 Lightspeed needs more room for wireless circuitry, but the result is the same. Like the wired G502, the G502 Lightspeed has a removable panel where you can add metallic weights.
