(It blends the color from the left and center sections of the rim.) Though it's an improvement, the customization isn't great: Weirdly, you cannot set a separate color or pattern for the logo. Unlike the Prodigy, however, the Lightsync allows you to set three distinct lighting zones for the left, middle, and right side of the rim. Like the G203 Prodigy, the Lightsync features two lighting elements, a light-up logo on the base and an RGB rim around the back of the mouse. Last but certainly not least, we should talk about the G203 Lightsync's RGB lighting, as it represents the mouse's primary upgrade. That's in the same ballpark with most modern mice in its class but not groundbreaking. The G203 Lightsync's proprietary 'gaming-grade' sensor tracks at up to 8,000dpi, and, like the Prodigy's, is accurate at up to 200 inches per second. That said, I can't remember a time when a Logitech product disappointed on the tracking front. While most premium gaming mice-particularly those from major manufacturers-tend to work fine, there is more room for variation at the low end of the spectrum. With a mouse this simple and inexpensive, the optical sensor is incredibly important. Though the mouse is technically lower than average, it feels like your hand is riding high. Rather than using a shape that guides your hand into a specific position, the G203 balances things out by simply raising the base of the mouse all the way across from left to right. In a category increasingly defined by 'faux ambidextrous' mice, which boast about providing little to no support for your hand, that is not a small accomplishment. Though it doesn't have the ergonomic hump near the base of the thumb that I look for in right-handed mice, it is not uncomfortable to hold. Despite the smaller shape, the G203 doesn't gain much of a weight advantage: At 2.86 ounces, it's an average weight for a competitive mouse, a bit heavier than you'd expect for one this small. Unlike those mice, though, a high-sloping base shape keeps the bottom of your hand from dragging behind your mouse when holding it palm-style.

That smaller stature puts it more in line with 'mini' esports mice made for claw-style grip players, like the Razer Viper Mini and the Cooler Master MM710. In keeping with the general trend toward lighter, competition-friendly mice, the G203 is smaller than the average gaming pointer, measuring 1.38 by 4.5 by 2.28 inches.
