My parents have the same Keurig you got, Spring. They use these daily (my Dad doesn't like any of the flavours in the premade ones) and it works well.

coffee at home - help me decide-imageuploadedbycurltalk1356805483.041243.jpg
I believe in manicures. I believe in overdressing. I believe in primping at leisure and wearing lipstick. I believe in pink. I believe that laughing is the best calorie burner. I believe in kissing, kissing a lot. I believe in being strong when everything seems to be going wrong. I believe that happy girls are the prettiest girls. I believe that tomorrow is another day and I believe in miracles.
