I have had them and they are great, the kids loved the look of them, though some of the younger nieces and nephews wouldn't touch them,
You can do that with regular potatoes as well. or another way that is fast, cut them up, toss with a little italian dressing or other favorite (it has the oil and seasoning already in it) put them into a pan, cookie sheet works or or other oven safe pan and back. (if I put them in foil I like to toss in some onion as well)
