It's very simple to use and it works great. For the first commissioning there just has to be guided, particularly Chromecast to install the application on the device to cast. Strangely WIFI connection is mandatory, even for caster content of a smartphone (such as photos) to a TV, so it does not pass through the internet. Hard side, the key reasonably warm but a little all the same, and there a cable for the power supply while the HDMI connector has a connector on its power supply. In summary, this is very satisfactory, but could be improved on some points of detail.
