Highest quality, I'm not sure what it is made of.
The white hot insert gives the putter a great feel. Though the putter may look "odd" it putts like a dream. I found that if I looked just ahead of the putter a few inches I could easily find the right line quickly and accurately. This putter has cut about 5 strokes off my game and I'm proud to say I finally broke 80 thanks to this putter. I highly reccomend it to anyone (especially beginners)!
I don't think I can say one bad thing about this club after all It's done for my golf game!
Great club, don't let anyone tell you It's only for women. Thats what my buddy was telling me and now he's looking into buying one after trying mine!
