Not bad, but there are better gums than this one. At the beginning is a big explosion of flavor and sugar like sensation, but after 5 minutes is gone.

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 :)

I was looking for gluten-free pastas because I am trying to eat gluten-free. However, on this pasta, even though it says 'gluten-free', says it contains 'semolina'. What is semolina? Quite frankly, it is wheat, and it is known to have high quantities of gluten.  I have never tried this pasta, so I don't know how good it is, but there is one thing I know- that will never change as long as DeBoles uses semolina in their products (and still dares to call the product 'gluten-free'. I can smell a lawsuit from here when someone severely intolerant thinks it's alright to eat this product.
