I am one of the few that DO NOT own one. My aunt got one for Christmas and I was like "ohhh nooooo, I must get this magical machine!!". My husband was like "nope, we have a coffee maker and it works fine. Don't be lazy". So now I am trying to find ways to break it........
I did have problems with my Special Edition model after having it about 6 months, but their customer service was amazing and they sent me a brand new one asap. All I had to do is return the K-cup holder basket from the defective model. (One of the CS people said that they have more problems with the Special Edition and the more expensive model than they do with the cheaper Elite model)
We did try the "My K-cup" which is made by Keurig. It was a total failure. Steer clear of this! BUT, I did find one called Ekocup (found it on Amazon) and it has worked very well. Hubby uses it since the K-cup issue gets "under his skin", lol. He gets to have Dunkin Donut coffee at a fraction of the cost.
All this being said, I love my Keurig - have one at home and one at work!
I love my Keurig but do also have some environmental concerns - I do wish they would make those k-cups recyclable I also have some issues with cost - if you buy them at your local grocer, they are upwards of 50 cents/cup or more with the specialty brands. If we have company, DH has a fit with about 8-10 cups being used! Yikes.
