PROBLEM: These have an artificial sweetener aftertaste. Not pleasant. I would not purchase them again. This the first Kcup hot chocolate I've tried, I'll keep looking.

SOLUTION: Aftertaste

PROBLEM: We have ordered this coffee on several occasions and have been happy with the it.  The most recent order seemed lacking in quality.  It was bitter and disappointing.

SOLUTION: Disappointed

PROBLEM: They look like a good idea.  My wife and I thought we would give them a try.  They are pretty easy to use.  The thing we don't like is the mess they make in the machine.  Even when to top is secure, they leak into the machine. You have to keep cleaning the filter basket or it gets sticky.  I would advise you to use something better like the E-Z Cup.

SOLUTION:
could be better
