Example Input: I will start by being kind, It is a good idea to save money with an item or concept like this. It makes good sense to use your own coffee beans and avoid the cost of the pre-filled commercial K-cups you buy at the store.  Now, I received my DisposaKups over a month after ordering them and put them to use.  I was immediately disappointed, filters did not hold very much coffee, It was a struggle to get the lids to fit together with the filter and outer plastic cup.  The coffee was very weak.  This product actually creates more waste in a landfill than the commercially made K-cups. The body and lids are plastic.  Normal K-cups do not have a plastic lid.  Notice they say 100% disposable....So put them in the trash. They are not recyclable = landfill.  They are not convenient, they are a bit messy, a pain to put together and still expensive.  Not worth it! There are better alternatives out there that will save you money, make better coffee and not go into a landfill.  Sorry, I wish I had better news, I think I will return these.
