I bought this glass ChillFactor in American stores here in Brazil even. Didn't work very well. But that wasn't so bad considering that the idea was really hard: do Smoothie straight in the Cup.
Comes with a glass, a manual and a spoon.
There is the Cup with lid.
Check the manual! The instructions are: put the glass in the freezer, put the liquid (a juice), tighten the Cup and is ready…
The harvest comes in a straw.
The glass has an internal plastic that freezes. This is the principle of operation.

Look at the video I recorded:
