I had one on my putter last year. Results started off very good but faded over time. I found myself gripping down lower and lower and locking the nub against my forearm instead of in my wrist joint. This created an issue where I wasn't "swinging" the putter and I was leaving a lot of them short. Think I'd have needed a longer, heavier headed putter to make this work more effectively. That said, If you're missing shorties or yipping, I think you should definitely give this a shot. I got really good inside of 5 ft with this grip.
