Attention: this is Not the original paddle. It is the best replacement out there that I have found. It does fit down on the post and will not wiggle back and forth but there will be a small gap between the paddle and pan of about 1/2cm. I have personally tested this paddle in a machine to be sure it mixes right and it functions as required.
The one you get may be a slightly different shade of grey depending on the stock I have at the moment.
