Logitech G604 Wireless Gaming Mouse | $70 | Amazon
One of the most annoying things that can happen in the middle of a firefight is having your mouse cable snagged when you’re trying to land a headshot. Eliminate the chance altogether with a wireless mouse like Logitech’s G604, which is down to $70 on a $30 discount. This mouse works over both Bluetooth and Logitech’s proprietary Lightspeed Wireless, which offers 1ms response times to eliminate as much input lag as possible. The 16K HERO sensor gives you accuracy, sensitivity, and range. The mouse also lasts quite a while on its lone AA battery requirement: up to 240 hours in Lightspeed mode or a whopping five months on Bluetooth.
