Reviews of Si5
Two great reviews advocating Custom Build capabilities with SeeMore. 
Jim M. review of Black Si5 Mallet - Only manufacturer who would customize to meet my needs
I tried to get two other putter manufactures to make me a 39 inch long putter due to previous back surgeries. Finally, I called SeeMore and Jim, their President, answered the phone. He had a putter made for me and due to the patented SeeMore system I am a better putter. I am 72 years old, play on a difficult private course in Florida, have a 13 handicap, and play at 6,600 yards. Thank you SeeMore.
 
Jimbo review of Black Si5 Mallet - Great price and value=results)
I had struggled with finding the right putter after having used several different brands and stiles. I won't mention the other brands but one was twice as much $$$$. I have been able to create better alignment, more consistency, and confidence with the Si5. The custom length has made a huge difference as well.
