The dongle is not overly warm, has a good transmission / reception performance, can be operated both via WiFi Direct and in DLNA mode and pair well with the home network, ie incorporate a normal HDMI-capable TV for example. From my Galaxy S3 Mini has the recommended app iShare Media personnel immediately works (even without integration into the home network) in DLNA mode, also judder in HD behind a wall of the room, on the notebook, however, I managed not streaming, despite all the approvals and enabled streaming under Win 7 and 8.1. Another disadvantage is the Chinese folder that contains only a few readable words. Googln for "CX-V3 Dongle Manual" helps. Switching modes DLNA (default) and Miracast may cause the smartphone to a dead end, because you will not come back from Miracast mode. For this, the small FN key must be pressed 2x (at an inserted USB host supply). The menu screen in 1080p is after plugging (USB supply not forget), although in English but very clear and contains clear explanations for coupling.
