Product review (4 stars): The original knobs are garbage!!!!!
They seem better than the original, so that should tell you about the quality of the original. Samsung should be ashamed of the quality of the knobs they are placing on their stoves/ranges. I've had to replace all the originals in less than two years. They appear heavy duty on the outside but the part that connects to the stove is plastic, the plastic they use is insufficient for what they were designed for. So far so good on the replacements but I will keep you guys updated.
