The suction cup does not move until you release it! The peel is perfection-thin enough to remove the peel, but does not sacrifice the flesh of the apple. The spiral slicer and corer is efficient and makes preparing apples for my granddaughter fun and simple! In fact, I am FaceTimed often to peel an apple for her viewing pleasure! She loves the peeled apples you can purchase and this does the trick, quickly, easily and safely!I used home grown apples that were small, bumpy and ugly! Johnny Apple’s removal of the skin made these ugly ducklings into beautiful swans!User error resulted in a misaligned core and I accidentally bumped corer once which stopped my process until I figured it out!I peeled, cored and sliced enough small (plum sized) apples in 30 minutes which made almost a gallon of apple butter. (It was a lot of apples!)I plan to try potatoes next. I have an electric peeler which had very little success with anything.I did not buy the unbranded intentionally because of the big job ahead of me. I’m glad I spent more money on the real thing.The Johnny Apple Peeler is a sturdy, easy to use kitchen tool that I did not realize how much I needed!I plan to buy another one as a gift for a very special granddaughter and her family!
