I have the 4Sat and thus quasi since he is now to buy for about 4 weeks. I am very impressed with the device. So far I have used the Netstream Sat Elgato with the expansion to a second tuner. The 4Sat is in every way better (if, of course, more expensive). Since he has a built-in multi-switch and Unicable support, it can be operated in many different environments. For me it works directly to an existing multi-switch and get four separate cable to its four inputs. The installation went quickly and smoothly. I just need to connect the device, turn it on and access via a free iOS app it. The app asked me about a few basic settings such as satellite and number of connected cables, then still directly loaded a firmware update and after about 5 minutes. I was able to get started. Since the 4Sat the only SAT support> IP receiver hardware encoding, you can look at this on mobile devices even HDTV. Who thinks now, that would not be noticeable anyway, let me tell you that the difference can be seen very well and very clearly. In addition, the image is very quickly at the screen, because the stream in the device is indeed converted, not only on your own handset. The EyeTV software also works seamlessly with the part together and with a little trick (just search engine strive), you can EyeTV even make it to use all 4 tuners at the same time, what means that you can make four shots at the same time and it works. However, you should then use Under no circumstances WLAN so that the plethora of data also comes to Mac. Other platforms as EyeTV on your Mac and the NetStream app on iPhone 5 and iPad Retina I have not tested, so I can not say anything to the receiver compatibility. But a quality device with a great feature set and HDTV on a mobile device is obtained here may yet provide no other supplier. I was part of the very confident and I highly recommend it.
