I was put in my place so very nicely - that my talk about these belong here where people can find it. And it's true ... so ....
Just this past couple days, Sunshinecruiser showed me her Robo Grips. I borrowed them to see which size I want - as they grip better than what I have, making it easier for me to screw on or off. Here's the link to them on Amazon: Robo Grip 7 At least to one size. This was the color handle of her larger sized one, so hoping it's the size I want. Haven't ordered yet, but will be.
On edit, I discover they are made by Craftsman - went looking for a Review and it makes me like them more. I just might buy the 2 piece set HERE.
Someone misunderstood how they work. When you grip them, the self-adjust to the size you need. There is no adjusting them. They grip beautifully in the trial I gave to Caroline's. And I went to the Sears site and bought that 2 piece set this afternoon.
