My experience with this device are ambivalent, on the one hand I am very satisfied with the workmanship, the design and the price, on the other hand the quality of the firmware is unfortunately inferior. The problem with the crash at shutdown I can confirm, as retaining frequent crashes during automatic switching on before timer recording, only one network separation persuaded the device back to work. Add to this the very confusing and not always intuitive menus and the absolutely inferior manual. I give it 2 stars only device here in the hope of a firmware update that fixes at least the crashes.
Before buying you should check in any case on the Internet if there is new firmware versions beyond 2.7er.
