Product review (1 stars): Don't bother.
This product arrived in a shrink-wrap package.  I tried to make things work but just couldn't get the clips to fit into the knobs so I dumped them in the trash.  FYI the knobs come without any numbers on them - instead product has 2 different sets of labels with numbers that you "clip" onto the front of the knob.  The picture on the product page shows  knobs with numbers attached but it's misleading.  You get 8 different number labels, none of which are attractive.  I'm a pretty darn good handyman but I couldn't get the plastic lips to fit into the back of the knob and I doubt if a woman could do it - it's very tough to do.  I dumped the package in the trash and got on line and ordered some genuine GE knobs from an on-line outfit - $10 each but they're going to fit and look exactly like factory installed.  So, if you gotta - you gotta - but I told you so.
