Delivery service UPS on top. My association with the application Cloub quick and easy. As against the Wifi in use is too slow and too slow Quad I say it's slow. It takes at least 10 minutes to display all files downloaded via USB, after average it takes 3 seconds to display each photo. I regret this purchase, it does not meet all my expectations. I'll check with the VAS to resume me this crazy product slowness, WD is not at the top for this product.
