The Good: cheap, maple axel cut short for a clean look. rolls great. light
The Bad: nothing so far
if you're looking for a cheap hub that is really well and reliable, i'd say go with the demo. been riding it for about 11 months now and still rolls like new. still rolls as smooth as the day i got it, even though not as long because the bolts are a bit tighter atm because of pegs but it should roll twice as long with out.
