Interesting company / "press release". So their CTO is named "Nasser G", their contact is named "Nick W". They have venture capital funding by an unnamed "private equity group". According to their website, they are based in Kansas City, Missouri but if you search the states business register there is no "Butterfly inc." The trademarks “Butterfly Labs” and “BitForce SC” do not exist in the USPTO database either...
Doesn't this seem a bit unusual for a company promising to deliver a $29,899 product?
