I don't have a problem with what cointerra has advertised so far, however claiming that they can make more in a day than knc can in a week is nonsense until they are making something. Buddy. Lol.
I simply put out they have the capability to produce more, not that they are now or plan to reach maximum output. Their plan is to become #1 US Bitcoin equipment seller, with non-stop output once they're up and running. As such, they have contracted several fully automated assembly lines, and can produce around 25,000 units per 24 hours of runtime. They also have one of the biggest order backlogs, so it will help to unclog once they begin shipping.
This isn't new news or FUD, this can be found online, in this thread, and others, as well as simply talking to their CEO and Assembly manager. It's part of how (and why) they secured their backing.
You can shrug it off if you like, but KNC takes it seriously. That's worth noting.
