Was only able to test some of the buttons as there wasn't a program I could find to test or assign all the other ones and I was not going to go through the trouble of installing WOW. Left and right click, page forward and back, and scroll button work as they should. lights up as shown in photo 2 and tracks fine. The rubberized coating on the sides had gone completely sticky so I cleaned it all off plastic is a bit cloudy on sides but in good condition. Overall condition a 7/10 or so. Just keep in mind it is only partially tested.
