Query: bad mixer for serious scratch djs

have had to replace the crossfader twice in barely a year! the fader im on now i have only had for about 2 months and it is almost useless now...not sure what the deal is but i dont practice THAT much. everything else is fine but since it's advertised as a "turntablist dj mixer" i thought i should let people know...
