Until I see a room full of them and proof of product or production I'm always leery about new mining equipment offerings. Looking back onto when ASIC Bitcoin miners first erupted onto the scene a number of years back I remember a number of startups claiming to have cheap, powerful and production ready miners but in the end just running off with customers cash.

Hopefully these guys actually deliver these running at the advertised speeds and efficiency!

Always do your own research of course.
