The establishment of the stroke has traditionally been accomplished through a somewhat clunky browser application. Meanwhile, Logitech has this almost 1: 1 converted into a minimally comfortable standalone solution. The device requires - if you want to achieve the convenience of the original remote controls - a lot of time and is only for frustration resistant nerds. The infrared sensor and the basic functions of remote control or keyboard are instituted with just a few clicks. When there are units but suddenly when you switch between different input and output sources, eg the CD player on the TV and from then on the Blu-Rayplayer etc. switched off and magically start, begins the great curse and Find. Of course it is possible to leave it turned on all the time switched devices even when switching back and forth. The function you have to find but once. A tutorial or a convenient personalization at initial setup (for example, "Do you want to save power or jumping back and forth?") Does not exist, however. Also preferences in the user interface can be adjusted barely. It would, for example, already a must that you could integrate certain buttons on the graphical user interface of the app (eg for turning the 3D effect on my TV) by default, no matter whether on the television just my PS4, the TV are output signal or BluRay player). The app manages play PS4, watching TV and video as three different tasks that need to be set each separately. Annoying.
