Something about the angle it plugs in at. One thing I don’t like about the cable is that I find it difficult to plug the micro USB plug into the mouse. The USB charging cable is about 24 inches long and is used to charge the Anywhere 2S. And I do mean tiny, I have been using Logitech unifying receivers for a long time and I am amazed how small that keep making these things. The Anywhere 2S is a wireless mouse that can connect to your computer using either Bluetooh LE or the Logitech Unifying Receiver which s a tiny USB dongle that connects to a USB A port on your computer. Inside the box, your find the 2S wireless mouse, a USB charging cable, a Logitech USB Unifying Receiver, and an instruction book. Check out my video if you want to see the unboxing. The mouse comes in three different colors, graphite, light grey, and midnight teal, however only the graphite color is discounted at this time. At the time I am writing this article you can pick one up for $51 on Amazon. This mouse retails for about $80 but it frequently discounted.
