Unfortunately, I can only advise you to buy it to avoid having to constantly open the access door to the mini-USB port, be it a laptop or tablet. But now Sony makes fun of the customer. This item consists of just a piece of plastic with another piece of plastic to be clipped above. There is not even a power cable !!! At 30 euros the support, I call it theft or marketing, but it's the same thing really. Prefer if possible magnetic cables "no name" that fill the same office for only a few euros.
