Task: Summarization
Input (English): First of all, I have owned a Keurig for about 4 years now, and I've tried lot's of coffee.  During that time, I have had an occasion k cup that didn't function correctly and loaded the brew with grounds.  I probably should have returned these before I bothered to open the second box.  Since I drink my coffee from a thermal cup, I can tell you that taking that last drink to find your mouth full of coffee grounds stinks.  I have had to throw out at least 6 cups of coffee.  Its a bit like Russian Roulette, and I've started straining it after I brew it.  I know that its not my brewer because it is not happening with the Green Mountain, Timothy's or Tully's that I also use.  The good cups are a bit weak for my taste, but the flavor is ok.  Definitely prefer not to waste $'s on a product with a manufacturing defect.
Output (English): These K Cups Have ISSUES - Coffee Not Bad
