However, the Logitec website clears advises the LED light on this mouse is an optical LED and is invisible to the human eye. I initially thought the same - I had turned on the mouse and could see it was working fine on the screen but noticed the LED on the back wasn't lit up. Pull it out and hey presto, there's your dongle (see the pics for details.) Secondly, there was also a comment about the little LED light on the back not working and the buyer therefore considering the mouse faulty. Take the back off and you will see a tiny section to the left of the mouse with the Logitec logo on. I was in the process of trying to return the item when I discovered the USB dongle is literally tiny and is fitted into the back of the mouse. I made the same mistake - my mouse arrived, no visible dongle included in the package. One relates to the mouse arriving without the USB dongle. I've written this to put right a couple of misleading commments in other reviews here although I can understand why they were written.
