All these mice are fully functional and come with the dongle, except the Logitech MX Anywhere mouse and the Logitech MX Master 2S. They do not come with a dongle, comes with a replacement cable and can be used via Bluetooth. These MX Master 2S mice are the Bluetooth edition. Some of the variations are new or opened, never used. Not all of the mice are use but they are all in decent condition. There are two variations for the  Logitech M650 L left mouse, so be aware before making a choice. Any questions regarding these mice, please let me know.
