I will not speak of the operation of the product as a result of a command error on my part I had to return it. It is not suitable for the Samsung Note 10.1 Tablet 2014 edition which has a different micro USB port of a previous 10.1 Version 2013. So beware, do not do me well take the time to read before ordering !! I just try to connect a USB stick well difficult it must seem forced and as I did not kept I did not want to emphasize more the quality of the product does not appear to meet you especially being estanpillé "Samsung" As for delivery while nickel was better than the stated time (one day earlier). To return all hat is nickel and easy following the amazon procedure. A postage label transmitted by email to stick on the packet and sending by post hop and 48h a credit confirmation email from my account of the full amount without any deduction for postage. amazon thank you for this reactivity
