The pineapple slicer does the job easily and effectively. I've only used it twice, so I can't be certain it'll last, but it seems reasonably sturdy. Using it is simple and it leaves you with a stack of clean even rings and, so long as you don't screw down through the bottom, a nice leak-proof pineapple "bowl.". The only drawback is that, depending on the size of the pineapple, it leaves a fair amount of edible meat on the rind. Considering how big most pineapples are these days, providing a larger diameter cutter would be good option.
