His name is Grant, and he was extremely responsive to my questions and comments. Here is what he says about the wringer:
I'm not positive that this is the right product for our needs, simply because I won't have that type of stationary object to clamp it to, and it seems to need that stability in order to put a shoulder into the job. But I like his style and his willingness to spend this much time explaining a product to one person. I didn't feel sold-to, and I'd like to think his responsiveness would extend to issues with purchased products.
