Ex Input:
The candy arrived with some white waxy stuff on it; almost as if it had partially melted at one point.  Tasted chalky.  Not interested in a partial refund.  Next time find a way to make sure candy is not stale.

I purchased this item as an alternative to traditional K-cups in an attempt to save money; however, this product did not work well in my machine. I followed the directions and read reviews to see what works best, but was not able to use the K-cups effectively. The cup itself is too weak and warps in my machine. I compared the shape before and after and there is a big difference; this K-cup seems to expand horizontally and vertically because the plastic is not strong enough. Also, the K-cup is shaped differently from the traditional K-cup. This is neccessary because it does not use foil as a topper, but does not seem to work. In the end, I had to clean up several coffee explosions in my kitchen to figure out how it works, but still could not use it effectively. Maybe I am not doing something correctly, but I'm sure there is also an issue with the product itself. While I do like the idea, I would not suggest purchasing this product until the bugs are worked out.

Wow, I had high hopes for a great addition to my low carb diet, but these rinds were very disappointing.  Tried several bags, but could not get the cooking time right.  Taste was dreadful, texture downright rocky.  I guess I'll stick to off the shelf rinds.  Won't be getting these again.  Can't recommend, and would warn of anyone asking for my opinion.
