Positives:
Long (175cm) and reasonable connection cable
Good Price
Neutral:
Like most of its kind, it docks is not stable, it wobbles and slips (A piece of non-slip mat helps against slipping, the tipping remains slight, because you'd have it all right then fix)
Negatives:
In the picture it looks as if two USB3 ports on the dock.
The front port is used only for supplying power to USB devices, excluding the upper connection is a data connection. (Which would not have a negative connotation, it would be in the product description)
