Lot of 10 Logitech G604 Lightspeed wireless gaming mice, all black. Each unit powers on and functions, but every mouse has a broken side button assembly as shown in photos, plus various flaws and wear on the rubber side grips. Sold as-is for parts or repair; no cables, receivers, or batteries included. Four are missing battery cover. Great bulk lot for someone needing replacement parts or willing to repair the side buttons.
