This is my 3rd pair and I have to say they have been great.  I have learned though that if you use these carts/needles with dirty vinyls, it will pick up dust like crazy and trap it in front of the needle.  When I put new vinyls on it was perfect as expected and had no pickup of dust.  I work on a regular basis at a nightclub using them 5 hours a night, 2-3x a week.
