Thanks for your return. I hope many people see your comment and don’t fall into this trap.

It is metallic only at the top – but the bottom is weaky plastic, with questionable quality of locking system I don’t believe will last long. The design make the top of the cup and locking puzzle messed with grinded coffee, as well as the bottom of the top grinding part – you must have to hold both part in your hands or, if you put the mechanism on the table after grinding, your table will be in mess, covered by freshly grinded coffee.

But aside of that, it doesn’t work. The mechanism is stopping in 7-10 seconds after you pressed the button. So, you will never gring your beans. Only manually if you purchased the extended set.

The support stopped responding to comments about this issue at INDIEGOGO and never responded to direct messages.

Stay away from this.
