Query: I felt duped

I was so excited about these gloves -- we eat lots of potatoes at our house and saving time is always a great possibility. Much to my dismay, I opened the box today and discovered that you have to BOIL THE POATOTOES FIRST!! How does that save time? I checked the outside of the box to make sure, and it says NOTHING about boiling the potatoes beforehand. Looks like a classic bait and switch to me. These will most definitely be returned.
