It takes your hands out of the stroke, no flip or twitch or hit impulse. Think of holding a little pencil in your fingers, and then think of holding a 2 X 4 in your hands. It is much harder to manipulate and twist the 2 X 4. It allows your hands to be more stable and still.
So it sounds like this would be a wise investment if putting is something you struggle with?
It could be depending on what you struggle with. It is great for people who have that hit impulse and struggle with inconsistent speed or too much hands in the stroke. If your problem is reading greens or aiming, it won't helped. Reading greens is learned. Most of the time, alignment and aiming has to do with eye dominance and the style of putter; depending on head/hosel shapes, people's aim can drastically vary.
Alright well I'm not exactly sure what I struggle with putting wise as I've never taken a golf lesson in my life and have just learned things on my own. I do know though that i very rarely make anything outside of 10 ft.
Sounds like I just need to play a few rounds and you could help me out at half the cost as a teaching pro.
