Product review (1 stars): Stove appliances can't stand the heat of hot stove top
The fasteners don't need to be colored, because when they show it looks like a crayon got stuck and melted under the knobs. Also the knobs are not the same as displayed, the package I received everything was backwards, on was off, low was high and 150 was 500 degrees. I unfortunately did not notice this until after I had installed them and threw away the packaging. Also for being knobs on a stove they cannot take the heat at all. One of mine has melted to the point it's sharp enough to cut someone while another has slumped over. I would not recommend this product to anyone.
