They’re definitely not all trash. I’ve had mine for like 5 years now and it’s mostly cheap plastic lol. It still works and not having to hand peel a single potato for years is lovely. The only issue I have sometimes is that it struggles with really big potatos but I just buy the ones I know it can handle or cut them in half.

If you have a kitchenaid you can also just get the peeling attachment if higher quality is a must for you.

Edit: If it helps, the one I’ve had for years is called the rotato lol
