The G502 Lightspeed launched as a 114g mouse at a time when most manufacturers, including Logitech itself, were attempting to market wireless mice in the 55g to 70g range. The oddity of this timing becomes even more strange when noting that the mouse actually ships with extra weights, specifically four 2g weights and two 4g weights that can all be slotted into the purpose-built compartment on the bottom of the G502 Lightspeed to add as much as 16 extra grams of weight.
That \"everything but the kitchen sink\" philosophy appears to be what Logitech ran with when designing the G502 Lightspeed. This mouse is loaded. It includes 11 fully programmable buttons, two-zone RGB lighting, a tilt scroll wheel with support for Logitech's \"Hyper-fast\" scrolling, its top-end Hero sensor, its low-latency Lightspeed wireless technology, and compatibility with its Powerplay wireless charging system. We'll cover each feature in more detail later. But, with all of them on board a wireless mouse with a 60-hour battery, it's actually impressive the G502 Lightspeed isn't even heavier.
It took several years, but Logitech became one of the first companies to produce a wireless mouse that had latency on par with, or even faster than, most of its wired counterparts. That technology continued to improve until it was standardized around Logitech's Lightspeed protocol. Like all Lightspeed-based mice, the G502 Lightspeed performs exceptionally, creating no discernible lag or latency when it's used anywhere within the 10-meter range of its wireless dongle.
The Powerplay system uses a small, optional puck that can be inserted into a variety of Logitech-branded mice. Once in place, this puck is able to receive power from the company's Powerplay-equipped mousepad, keeping wireless mice topped up at all time, without ever having to plug them in.
Having personally used the Powerplay Wireless Charing System with several mice, I did enjoy its ability to keep wireless units charged with zero thought needed. However, I stopped using it myself because it limited me to the very few mousepads that come with the system, none of which were large enough for my tastes.
That said, I'm still glad to see its inclusion here, and in all future Logitech mice. This is thanks entirely to third parties doing something Logitech itself should have done years ago: using the Powerplay slot to create a charging dock. These small units can be had cheaply (usually under $30), and provide any Powerplay-equipped Logitech mouse with a quick-connect, magnetic docking station that will keep it topped up with almost no effort. They even include a slot for the mouse's wireless dongle. If you own any Powerplay-equipped mouse, I'd urge you to get one of these inexpensive charging accessories.
I've already made it clear that the Hero sensor and Lightspeed wireless technology in the G502 Lightspeed were essentially flawless. While I can't heap quite the same level of praise on every other aspect of the mouse, I will say right at the top of this section that it is an excellent mouse for any gamer that's willing to accept its mass.
All of these extra buttons feel acceptably tight and precise, and all feel as responsive as anything, wired or wireless, I've ever used. While I've made it clear across multiple reviews that I'm not a huge fan of Logitech's continued use of the same Omron switches it has been relying on for years, the G502 feels as good as any Logitech mouse, and more than crisp enough for any but those with the most exacting standards for the tactile feedback of their clicks. 1e1e36bf2d
