The device is quite cheap and promises a lot of functions, but unfortunately it's completely immature. It depends on repeatedly and has to be brought back by a reset. Stored data will be lost. It recognizes my 2 3 external hard drives not (USB 3.0 and USB 2.0). The remote control is badly processed. It reacts very slowly to entries.
Conclusion: It does not cost much money, but a lot of nerve!
