Negative I find the following points:
The record a program is only possible if the device is connected to the Internet. An external hard drive / USB stick is formatted so that you can watch the recording even on TV.
The TV responds when switching a bit sluggish.
Creating station lists eg favorites is very cumbersome and lengthy.
The settlement via Amazon was -as always- very good. The unit was slightly damaged at the base and Amazon responded immediately to my mind.
Conclusion: good equipment, good value for money at the offer price. An asterisk I draw from because of the negative points above.
