Coffee Jack - 9 bar pressure?

Recommended Posts

Has anyone seen this gadget on indie gogo?  I have no idea about these kind of things but looks intriguing, claims to achieve 9 bar pressure in a portable little unit.  Does this seem possible and would it produce an "espresso".

I tested something much better made than the CoffeeJack and it worked on the same principle...it was crap.

Crap, sorry guys I did do a search and didn't see it, I'm on mobile, don't know why it didn't come up 🤔 I was very skeptical myself, so just wondered about it. I'll try and search better next time. 

Edit: Seems I put a space in my search Coffee Jack 🙄
