Bests & Worsts Reviews from Amazon

Finally a reusable K-cup that produces a cuppa Joe strong enough for my liking (I like it just short of Starbucks strength). I've bought and returned numerous reusable cups. They either didn't hold enough coffee or sent the water through too quickly rendering a cup of colored water. And all sent sludge into the cup if used without a paper filter. This cup solves the strength problem but not the sludge, thus the 4-star rating. You can't use a paper filter because of the lid's locking system. A filter that would fit fully into the cup would uselessly let water and coffee grounds flow over the top of the filter. My workaround is dispensing the coffee through a Melitta single-serve pour-over system rather than directly into my cup. Now I have a beautifully clean strong cup of coffee. ::smiling:: I ask my coffee purveyor to grind at #9 and use 2 rounded tablespoons for a mid-sized cup.For a large cup, fill to the travel mug mark. Fill it fairly loosely; tap it only once on the counter.
