The only drawback - and that's really disturbing - is the slow app (on iPhone 6 tested). Extremely long waiting times when starting the app or TV channels for the recording you have to accept. Since remote programming lasted by 10 minutes of which 9 are not "wait" for.
Conclusion:
I release my Samsung Blu-Ray Player with friends in retirement, will try a lot more in the future with this device and am particularly pleased about the EPG skills and the simple recording function. The app will hopefully verbesset - then I have no criticisms.
