I will start of by saying that I should have checked the dimensions first.... The Seller does list them, so it was my own fault for believing that if it fits 'most putters' rather than checking for myself.
I am currently choosing between 4 different putters and none of them have a small round grip on them, so I guess I'll just have to throw this away and go to a golf shop with my putter(s) to get the right type and size.
A lesson learned... Perhaps this product is perfectly designed for ladies' or juniors' grips, but not for men's'.
This little tool is a godsend to anyone with back problems. No stooping to get the ball out of the hole. Everyone with back ache or bending problems should use it. A tip! If your golf bag is small (or full of clubs) you might want to fix the tool on to it with a couple of drops of supaglue to prevent it from falling into the bag.
