A quick note here, the "K" type brewers give you a better brew than the common drip type coffee makers. DD and SB brew their coffee between 196 and 200 degrees Fahrenheit. Some “K” cup models go up to 197 degrees Fahrenheit. I usually drink DD or SB while the rest of the household is like whatever. I was on the fence about the system up until this past December when I got one from a DD at no cost to me. I use that one in my office and my wife bought me one for the house. We have had no problems with either unit so far and easily brewed over 700 cups in the one at the house since January of this year without any issues. I will say that we only use bottled water being we have a well at the house and the office. I know people in our area that have complained about the scaling and I can see in the posts here that is an issue. The “K” type system allows you to brew tea and hot coco as well. When the nieces and nephews come over in the winter to go sledding or skating it’s pretty nice to have.
