I used this mouse for about four months and then stored it after buying another one. The mouse feet have been removed. I will include 30 universal arc1 mouse feet, so please feel free to use them. The accessories are as shown in the photos. The black item is the 8k dongle, and the white item is the included receiver. There are no operational issues, but there is a stain on the tip of the cord that connects to the dongle. There are no problems with its use, so please purchase only if you don't mind. If you have any questions, please leave a comment.
