Product review (1 stars): they also easily break. Stay away from this product
Worthless piece of cheap plastic. I ordered one and in less than a year, it is broken too. What a rip off by the people who manufacture this equipment. Cheap! Cheap! Cheap stuff. It is supposed to last the lifetime of the product but this is not the case with these knobs. Granted they fit perfectly. But so what, they also easily break. Stay away from this product.
