You don't have to shop Logitech if you want a lag-free gaming mouse. Corsair is launching its own take on the concept, the Harpoon RGB Wireless, at CES. The peripheral gives you the option of ditching USB (which remains an option here) for a 2.4GHz Slipstream Wireless connection that promises less than 1ms of latency. If you miss a shot, it probably won't be due to the delay. There's also Bluetooth in case you'd like to quickly switch the Harpoon to your laptop.
