I think it was a highly-anticipated knife and when folks got them, they decided it didn't meet their needs as well as they hoped. I don't think it says anything bad about the knife, just that it's hard to judge what you are getting when you buy online. I was lucky. I was able to handle one in a knife store. I could tell right away that even though I was impressed with it, there was no way I'd ever be comfortable trying to use it unless my hands decided to grow some more. The 550 was closer to a good fit, but even it was a little too large. I've decided that with the ZTs it's probably best for me to handle them before buying. Come to think of it, that's my preference with any knife these days. Fortunately I have a good knife store about an hour away that carries a lot of the knives I would be interested in buying.
