The WD15 was a joke if you get power spikes, you would sometimes have to wait a few minutes or the next day for the device to reset itself so that it can function normally.
The WD19 started looking better than the old model but recently they just stop working from one day to the next.
I just hope one day they see the light because I just cannot understand why their docking station has so many problems.
I think it's time I start looking into a better reliable docking station.
