His claims have been proven wrong by a number of experts in a number of scientific tests. A putter with 0 degrees loft makes the ball bounce at the start regardless of the length of the putt. Bouncing is not a good thing.
He also has more weight in the heel of the putter, and a very flat lie angle which works against physics.
I like the design idea of the club head, but with the 0 loft, heel weighting, and flat lie angle find it useless.
Better to get yourself a Kramski putter!!
