I was very happy to make my piston churros. The mechanism worked fine, super effective! But one day the rod pierced the plastic tip. Shame !!! I can not use it. Why plastic ??? The plusparts pistons have the plastic caps, but him there is much more expensive. The old model as Sawa (mark Sweden) have stems with ferrules Metals (this is for life !!!) I went on ebay or etsy and I just ordered a 71 SAWA 2000 "cookie press" made 60-70 years in Sweden. To make the churros, cookies etc. Too bad Amazon does not sell its products.
