The object works fine, if either USB 3 or, failing that, in USB 2. Practice for tablets and small PC without ethernet socket. USB 3 is not is obviously not important if you do not have a USB jack 3 on your computer (it is still rare and where there has usually already there an ethernet jack), but the price amounts to the same thing only USB 2, then the advantage of this one is that it prepares for the future. Of good quality, small twist of the cable at the RJ45 housing, it will not force it but it's really the only downside.
