Input: Consider Input: I love little white kernels of popped corn.  This was good stuff, but I think I'll try a larger white kernel to pop next time, my preference.

Output: 4


Input: Consider Input: Neat concept. Other contraptions to use your own coffee have prepunched holes and are designed much differently than the K-Cup. This is like a do it yourself K-Cup. However, because this consists of a disposable cup, filter, and a cap and is punched by the brewer, I would not be surprised if this mechanism infringed on Keurig's patents. Oh, and the video review submitted by the other reviewer looks suspiciously like the video on the manufacturers website :)

Output: 3


Input: Consider Input: I tried this before having normal red tea so I waited to review. The flavor still rings in my head it is earthier than rooibos tea and less frity. The color is that of muddy water, and it has the grittiness and viscosity of it as well. Well worth every penny.


Output: 5
