If you go to grocery store and purchase a pineapple that is already peeled and cored, you always pay extra money. You don't have to anymore. That is exactly what this product does- cores, peals, and sections. Ease of Cleaning Top shelf of dishwasher. This is a dishwasher safe item. No problems. Durability You must use a little bit of elbow grease when using this and it stays nice and strong. As you are pushing down on your pineapple, you don't feel it wiggling or that it might break. It's made very well. Design The design is no fail. You take you pinapple and cut off the top and the bottom, so the pineapple lays flat on a cutting board and you are able to put the pineapple slicer flat against the top. You push down evenly on both sides using the handles. If you are short, you may have to stand on something because you need a little bit of strength to push down. I always wiggle it a little bit as I am pushing down to keep the sides even. Once it is through, pull out your cored, cut pineapple!
