Multi-Functional Kitchen Vegetable Cutter Home Use Potato Thread Slicer Hand Protection Thin Slice Tool Japanese Style

Pretty good, easy to use.

It cuts pretty well, using the finest setting. The round part doesn't really serve much purpose. At first, the potatoes cut nicely, but as they got smaller, it became trickier to handle, and it was easy to scrape my hand. When there's just a little bit left, I either can't cut it or have to deal with a rough cut. The round part can't fit larger potatoes, but if they're too small, they don't cut well either. Overall, it's decent.
