This club is my first experience using a counter-balanced putter, and I have to say I'm liking the performance thus far. Lag putts and distance control has always been a weakness of mine. No more I think. With the extra weight in your hands or above them (hidden and adjustable within the putter grip), control and a smooth and even stroke comes so much easier than the putters of the past.
The open box Nike putter I ordered arrived and the first thing I noticed was a 3/4 tear in the headcover. There also seems to be a small defect in the sole of the putter head. Probably why this club was returned to the manufacturer? Don't bother trying to contact global golf by email as they don't respond with any answers to questions. Shipping time is incredibly slow. My package took 12 days to arrive in MN. Also had to call to get tracking numbers because I never received any.
