I purchased this during the preorder phase late last year and just received it. Since then I have realised I enjoy the filter coffee I make as it cools down, hence no need for this state of the art mug.

I paid USD 258 which included USD 70 shipping (amazing how expensive shipping from the US is these days). This equates to $350 but I am willing to cut my losses and sell for $195.

I also got an extra charger which means I could have left one at work. I have not opened any of the packaging so the unit can be shipping at buyer's cost perfectly.

Let me know if you would like any more information.

Thanks!
