You are offerding on a lightly used Logitech G 602 Wireless mouse that has been lightly used and is in great condition. In my use I never noticed a delay in response time even though it\'s a wireless mouse and I had no problems with it whatsoever. I\'m selling it because I upgraded to something lighter. The mouse comes with the original packaging and USB extender cable along with the USB plug-in for your computer as pictured. I\'ve also included two batteries for your convenience. Thanks for reading!!
