In its diversity of functions is unique in the market.
Unfortunately, there are no competing products from other manufacturers.
In the various special functions there are quite potential for improvement:
Trying my of artists and albums in directories structured music collection from the PC via a USB stick to the hard drive
copy failed because the files must all be in one directory.
For photos, there is a similar problem. Here you can indeed read subdirectories, of the sort but is subsequently
left on the hard drive anymore. To sort the hundreds of images again in the device would be extremely annoying duplications.
The alternative is to call them via Wi-Fi when needed by the computer.
This works quite well, but means that it specially, the computer must be running.
Actually, I had bought the model with the 1TB drive to avoid this.
(When viewing the recorded programs I've also missed a function that I know from my old Sony-HDDRecorder.
To skip commercial breaks you can here jump button more than once per 60 seconds to but by repeatedly pressing the
Key jump variable between 30 seconds and several minutes.)
Update: Thanks to the comment of a reviewer I have now found the Time Slip button.
If the weaknesses described would not, the device would certainly deserves 5 stars.
So unfortunately only 4. I'm hoping for a software update.
