It does what it says, which is a big plus in the budget range of networking equipment :)
Additional pros: this is a compact and stylish looking device, so if you want to mount it in a visible location (e.g., your home office desk) you won't shudder every time you look at it.
Perhaps a con: it's very, very light – which means the weight of cables can drag it about. If you want the base to lie flat, you'll probably need to employ ghetto hax like bluetooth. For me this is minor – it's mounted behind my office monitor – but cable management might need a little extra thought.
