I'm not a huge fan of the looks of this putter. However, there's no arguing with the performance. The combination of the head design--white, with the ball-shaped hole in the back--and the center shaft make this putter the easiest thing to align that I've ever used. (For what it's worth, I play right-handed, but am a lefty, with left-eye dominance. I putt with the ball right inside my left instep, so that my left eye is looking straight down the line of the putter shaft. This design fits my eye in that position perfectly.)
In addition, the insert on the face gives it a soft feel that translates into good feedback off the face. I've used high-end Bettinardi and Cameron putters, and I prefer the feel of this one.
It's not the coolest-looking putter on the block. But for me, this thing does everything but make the stroke for me.
