Appears to have been a return that was resold. The box had a slight tear where one would expect such tears if it had been opened earlier. But. I agree to resale as long as the product looks new and performs as expected. And this one does. I just felt I should note the look of the box for those who might be interested in return/resale practices. With this device I can connect up to four USB devices and connect it to two different computers via USB. , so both can use the same devices (individually, of course). The backlit button is pressed when I want to switch devices, the blue one is my laptop and the green one is my desktop. Installation took less than a minute, no power cord required. What a joy that two have two keyboards, two headsets and two mice to switch between when I switch machines. In my home work environment, my work laptop and PC are on the same desk and both use my upgraded widescreen monitor, so this device is a good fit for this style of work. If I had any complaints it might be that the USB cables were a little short, but I've still managed to make it work well and I can always get my own USB connection cables if needed. If anything goes wrong in the future I will update but so far this thing is working as advertised and my work station is down three devices cluttering my space. Very satisfied. The delivery was fast as usual. Hello Flyvus!
