Product review (5 stars): Well, it works better than the original dough hook
I've never felt that the original dough hook did it's job.  Seems like the dough just spinned around the hook so often, rather than kneading the dough.  I've used this new one several times and I feel it does a much better job of kneading as it spins in a manner that makes it almost impossible for the dough to just ball up and spin.  However, if one does very wet dough, then it does not work as well until the dough begins to firm up, so I use the paddle and original hook until the dough firms up enough..............Glad I bought this product....................Quality appears to be good, just don't put it into the DW, as said.  It also says to not use a higher setting than 2 on the KA mixer.
