Fine. But after eight years of trying to cook with these things, I don't even like the look of them anymore. For one thing, they NEVER sit in the neat and perfect stack as shown. Never. They're always willy nilly. Willy nilly is their natural state. And when stacked, they're even less functional than usual. Only the top-most cup (teeniest) cup is easy to access. It takes two hands to dig down to the one you likely need. And they're heavy. And they're breakable, so they force you to worry about chipping them when you're busy trying to think about cooking. It's annoying.
Finally, the handles are pretty useless. I don't have fat fingers, okay? My fingers are perfectly svelte, but they don't fit through these handles. So I can only assume the handles are entirely for show.
Sigh. But they were a gift. Not from something I like or am even in touch with anymore, but still. It seems silly and wasteful to buy more measuring utensils when, with a little effort, these DO do the job sufficiently. I mean, it's not like the measurements are off or wrong or anything. The cups just annoy me.
Nigella, I have no problem with, by the way. I've even positively reviewed one of her recipes. (Chopped ceviche. Yum.) I don't hate her. I just hate her measuring cups. If you're serious about cooking (or if you cook on a regular basis) use regular stainless steel measuring cups with substantial handles. You'll thank me, I promise.
