If your DH likes to grind his own beans to make coffee sometimes or is hooked on a brand that does not come in K cups and is picky about his coffee- there is one trick it took DH a lot of time and internet surfing to figure out. He still likes to do his own coffee in addition to all the Keurig varieties. He has found several types of K-cups he really likes, but he also still likes the coffee he used to buy and grind before the Keurig. Several brands sell a cup for you to use in your Keurig to use your own coffee grounds. We tried a couple of different brands of cups for doing that, and the coffee wasn't up to his standards using those cups. It did not taste like it did with his old coffee maker, it was weaker. After much trial and error and searching the internet, he found a trick on the internet to make it taste right. He uses the EZ cup brand cup. He keeps a used K-cup (it has to be used so the hole has been poked in it by the machine) and he cleans out all the coffee from it really well. Then he cuts the used plastic K-cup down to about just 1/4 or 1/3 of its regular size. Just enough to basically cover the bottom of the EZ cup and have a little side left. Then he puts that in the bottom of the EZ cup pushing down slightly and puts the filter on top of that. He says the point is that the EZ cup and other brands let the water go through too fast so it doesn't get the full coffee flavor. When you put the bottom of a used K cup in, it increases the back pressure a bit and gets it to flow though at the rate it should to make the coffee right. He uses he same used K-cup bottom for several uses with the EZ cup. He says it works great. I don't think most people are quite as picky enough about their coffee to go through the effort- especially when there are a ton of K-cup options!

I'm sure if that is something your DH wants to take the time and effort to do to use a certain coffee type or brand that doesn't come in K-cups, you can find a video or better description somewhere on the internet.
