The goods came to the RB quite quickly in 23 days constantly tracked by tracking postal shipments, the packaging is good, the product corresponds to the description there is video and audio, though the drivers are on Ang. And Chinese, on the disk only drivers installation instruction is missing, the seller is sociable and watchful, I recommend.
Module works. If you use it under a draw tablet or gaming its not fast enough. Movies and normal office stuff is okay. Sometimes after computer standby you have to "replug" the usb because it does not enumerate any more. Driver on disk must be installed first then plug the module. So if you need a second or more screen without high speed it okay.
Product works as described. Used two USB composite device with connection to a third monitor using hdmi and a fourth monitor using vga via a docking station connected to a laptop. It works like a charm. Well done. Will recommend this product to others.
