Query: Great idea - Terrible product!

Thank goodness I didn't buy the My K-Cup separately. It came as part of the combo pack with the Keurig that my in-laws gave me for Christmas. I was pretty excited about being able to use regular coffee grounds with my Keurig--I looked forward to having more variety, a backup if I ran out of K-Cups, and a cheaper alternative.Well, it has been nothing but a disappointment. There is no way to use this thing that water doesn't leak all around the sides and leave me with a very weak cup of coffee. I have tried all the tips from other reviewers about how to pack the filter with coffee, but none of them work.There is another similar product, the Solofill Cup, which gets much better reviews. I am going to try it...Don't waste your money on the My K-Cup!Solofill Cup, Refillable K-Cup For Keurig Brewers
