"Looks pretty easy to use, slow 12-15 MBytes trans speed"
Pros
Very simple to set up, looks cool.
Cons
Feet keep coming out, cables tend to lift it up from desk if back too close to wall, sustained transfer rates very slow. With cat 6 cables, gigabit network cards, gigabit QNAP Nas I could only achieve 12-15 MBytes - that is 96-120Mbits per second.
Summary
You get what you pay for. For A$100 its OK. I should have bought a better quality item. Using all the right cables and network cards and fiddling with network card and NAS settings didn't help.
