Getting wireless "right" on a gaming mouse is no small task. First, the wireless delay should be as low as possible (<1 ms). Second, polling stability should mostly be similar to wired mode. Finally, battery life should be high enough to last through at least a week of average gaming and general usage. The Corsair Dark Core RGB Pro manages to do all of these things and therefore joins the rather exclusive club of wireless excellency, which only included Logitech and Razer thus far. The most impressive part is the fact that Corsair has enough confidence in their wireless technology to where they didn't even bother to include a wireless extender—not even Logitech or Razer go this far. All my testing was done at a minimum distance of 50 cm at all times, yet the wireless connection remained flawless throughout. Although the battery life of the Dark Core RGB Pro is decent (36 hours without illumination in 2.4 GHz mode), it's quite clear that Corsair prioritized tracking quality, which is fine in my book—having hundreds of hours of battery life is of little value if the wireless operation itself is subpar. In order to prolong battery life a little further, operation in Bluetooth mode is available too, which is a nice option to extend battery life when not gaming. Personally, I'm very much looking forward to seeing which mice Corsair will be outfitting with their excellent wireless tech in the future.

The Dark Core RGB Pro does well in many other areas, too; sensor performance is great, button quality is high across the board, and the scroll wheel is fantastic. Its contoured right-handed ergonomic shape makes the Dark Core RGB Pro a great fit for palm and claw grip alike, while the grippy materials and nicely gliding feet result in great handling. There's also the option to swap the right side panel for one with a thumb rest. Furthermore, Corsair's iCUE software offers an impressive range of options, along with highly customizable RGB lighting effects and the ability to program all of the available buttons to one's liking.

Of course, all of these features have a price—the weight. Although not out of line in comparison with the competition, the Dark Core RGB Pro quite simply is not a light mouse, the good weight distribution notwithstanding, and while iCUE is rich in features, it's not entirely intuitive to use, and the RAM usage is nothing to be scoffed at either. Lastly, click latency is incredibly low, but it too comes at a price, which is the occurrence of slam clicks—the debounce delay is so low that clicks are registered when gently slamming the mouse on the pad without even clicking. The best solution for this would be to offer an option in the software like ROCCAT does: either super-low click latency at the expense of unintended clicks or slightly higher click latency without any unintended clicks.

Speaking of price: Although an MSRP of $79.99 isn't necessarily a bargain in and of itself, it most definitely becomes one when looking at the feature set and the wireless quality the Dark Core RGB Pro brings to the table in comparison to the competition. Hence, I'm happy to give the Dark Core RGB Pro both the Budget and Recommended awards.
