Product review (5 stars): Crafty Product
It is difficult to identify the correct replacement part for old appliances from Internet descriptions and this product is no exception.  The product delivered appears very similar to the broken one I needed to replace but the threads were different and it wouldn't work as delivered.  Fortunately, I have some mechanical ability and tools so I went to my toolbox, selected the correct "tap," and re-threaded the knob.  Easy job, works fine, looks fine, and I'm okay with it.  But, it would have been nice if the product description had mentioned the thread size (1/4 X 20).  I may have made the purchase anyway because it is a good quality product and great price.  The seller earned my respect and my satisfaction because the problem was not due to anything he did wrong.  But, unless your a little crafty be careful about buying this kind of product without better information.
