Query: NOT for Hamilton Beach Single cup Brewer

I bought this product about a week ago and it absolutely DOES NOT work in my Hamilton Beach brewer. If that is the coffee pot you have (model 49970) then do not buy these. Its not just a weak cup of coffee, its basically water. I tried regular ground first and then espresso ground and neither worked. They are also a pain to fill up because they are so small and get coffee everywhere. Don't get me wrong, they SEEM like they will work because they fit so perfectly into the compartment. But they don't. I loved my coffee machine when I first got it because the Senseo pods were so great but now that they aren't available anymore and these stupid things don't work either its basically a worthless piece of junk sitting on my counter.
