The attachments work as advertised and we've made several batches of noodles already. The fact that they can be washed in water makes it very easy to clean. Other attachment brands are not able to be washed in water, which is why I chose this one.
My only wish was that the cleaning tool it came with had a tapered end like a wedge to pick out the dough in the nooks and crannies of the attachments. It's not too big a deal though and I use a toothpick to get the job done.
