Product review (2 stars): Works, but not like the original.
I had the same issue as a previous reviewer--although the knob technically fits on the bit that attaches to the stove, it juts out much more (about a centimeter or so) than the original knobs. This isn't a huge issue for functionality (it works just fine) but its a bit of an eyesore and might pose potential cleaning problems (looks like food or grease could easily fall into the gap). Its also slightly shinier than the original knobs, though this might just be a function of the original knobs dulling from use.

If you're finicky about fit or appearance, I'd skip these and buy direct from GE.
