This mouse is in rough shape but powers on and seems to work fine. I am not the original owner, this came to me in a storage unit lot. The main buttons work fine, scroll works, tracking works, i did not test all the extra buttons or install any software. as shown in the photos there are imperfections in the braid around the cord, the scroll wheel is missing rubber parts, there are many scuffs and scratches. because of the rough condition and untested buttons this mouse is sold as is. thank you!
