It always had side to side slop, didn't reduce the throw enough, transmitted noise/vibration, after 6 months the bearings that they use instead of bushings were seized up and the knob height was increased. I finally got fed up one day and modified my stock one.
I've been on the V forums for 5 years and have never heard the UUC one called the best. If you search long enough there are threads on this forum that compare the top ones. There is even a spreadsheet with all the comparisons in one place. These comparisons are from people who have either had multiple brands in their vehicle or have tried others at different V get togethers.
