They used to be 2.5 around here. Even with the huotui. (Or maybe 3 - I may be misremembering.) Competition sprang up a few years back in the form of two other cooktops producing what in my opinion was an inferior copy. Still, the dude diversified. He has optional huiguo rou to add now and some other stuff that might, bizarrely, be noodles. Still seems more like a luncheon object than a fast breaker.
I went supermarket shopping today and once again despaired at the packaged crap available. I don't know what it's like in other places, but here there's a vast array of what seems to be basically the same product - bite sized, preserved and overly syrupy... stuff. Technically, the number of products is huge, but somehow not. They are to eating what instant noodles are to dining.
Pfft, I can't substantiate the opinion. It's just a sense of no variety.
