To stick itself:
The build quality is really not good, everything rattles and shakes. For the price I had expected.
However: listen to radio at all is not the stick. The reception is very very bad - to get a channel without noise purely is almost impossible.
I'll send the stick back - if I am eventually get out of Auto-customer response loop and the seller gives me the return freely.
Conclusion: Not recommended should you so want to hear radio.
Addendum:
I have requested a return for this device. The seller then asked to send a photo of the defect. When I pointed out that one can not take a photo of a poor radio reception, the return was denied with an automated email and concluded the process it.
