Ex Input:
The pineapple coconut combination is refreshing. I especially like that there is no added sugar. This is a welcomed change from other brands.

Ex Input:
Yes, tasty -- but it takes a little getting used-to.  You have to like coconut to like this snack item.  That taste quite overwhelmed all else, for me.  I found few chocolate chips -- maybe they were all taking a rest when my snacks were baked.  Anyway, it's a chewy but tasty item worthy of your consideration.  Give it a try.

I was looking for a simple and inexpensive way to provide my own supply of "home made" K-cups. This product is all that it is described to be;fairly easy to use and does not adversely affect the cup of coffee. Clearly, the cups and lids are in fact reusable albeit a little messy. I have used all 50 filters so I am at a point where I need to decide if I want to continue on with this regimen or go to plan B. I am electing to try one of the reusable style cups that don't require the use of a filter. My hope is that it will be a little quicker and less messy to use. However, if plan B does not meet my expectations I can always order another supply of filters and continue on with this DisposaCups system.
