In good reception conditions (western German city), the mini-telescope antenna is sufficient great. Both on a Samsung Galaxy Tab Pro 8.4 as well as on a Samsung derivative (Hyundai 7Ts) does the receiver with the appropriate software properly. In addition to the supplied mini-antenna is also a small kabelverlängerte rod antenna, which can be connected flexibly with magnetic or suction cup. Disadvantage of the recipient micro-USB is that a simultaneous power supply for most devices is only possible via an adapter (the Hyundai is the power supply extra). However, the power consumption at medium brightness and volume is very low, so that I could watch over four hours at a time when still enough remaining capacity. After a short service life of the recipient unfortunately works at any of the tablets more or the Galaxy reports in nice change "USB Connektor connected" and "disconnected ...", which has the construction of the station list is no longer taking place. While when connecting to the Hyundai launches the app automatically (ie, the device is generally recognized) but it is not a device displayed in the app. I'll send in the receiver in the hope that it was a unique phenomenon. Then there's 4 stars. Otherwise only two. Addition: there was no substitute because no more available. So only 2 stars.
