Ex 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 :)

My daughter loves these snacks and can't get them in China where she is working now so I ordered them for her. Very satisfied and she was very appreciative.

i was disapointed in this salt. since it is a truffle salt i expected to taste at least a hint of Truffle but didnt. if you want a really good Truffle flavored salt order Fusion Black Truffle salt it has a wonderfully strong aroma and great flavor!
