Product review (1 stars): They melt!!
OMG. I want to take these out back and light them all on fire. I had my home professionally cleaned which they ruined my original knobs by cleaning all the numbers off of them which brought me to this set.

I second guess the oven temps because it seems things take longer to cook. I need to buy an in-oven thermometer and ditch these things and just stick with the old ones. If you use the oven, the stove top knobs won't work because the heat from the oven heats up the core thingy and they just warp/melt and spin. My oven one falls off EVERY time i cook. They make me nuts!! I literally hate them. Do not buy
