Product review (1 stars): Junk, don't waste your time.
I didn't need anything fancy so I didn't care how they looked, only if they functioned. Wow... These things are junk. They do not stay on the stove (if you barely bump or touch them they will fall off) and the metal looking piece around the knob with the temperature/off slides around so it does not line up in the correct spot. You can slide it back to the correct spot, but who wants to mess with that? One more thing, I have a gas stove, and the oven knob started to melt some when in use. For now I super glued the knobs to have something there, but will spend the $20 for decent ones in the store.

Oh and to top it off, not eligible for returns. Sounds like the seller knows they are junk.
