Product review (3 stars): Glass lid cover knob is marginal, but does do the job.
This glass cover knob is really cheap looking. The metal is really thin and the rubber part is uneven. As other reviewers have mentioned, the screw is not long enough to attach to my Oneida glass pot cover. I had to buy a longer screw at the hardware store. However, with the new screw, the knob does do the job and that is the most important thing to me, because I really like my Oneida pots and pans.
