Product review (4 stars): Exact Replacement But Not Durable
These are exact replacement knobs for our range.  The problem is that they are made of plastic and do not last very long before they dry out and break.  The chrome finish is not really a chrome finish but a chrome looking paper which can loosen and come off over time. The manufacturer should make the knobs from a more durable product.  The next time I purchase a range I will inspect them more closely.
