I bought my first one 6 months ago and I'm on my 3rd one now through warranties. 2nd one didn't heat up or give right cups and only gave out about 6 oz on the 8, 10 and 12 oz ones.  I'm on my 3rd now for a few days and it puts out 12 oz on the 10 oz. I want my money refunded and I will never buy Keurig again. Fix these issues Keurig or you'll be out of business. I would not even give 1 star but it makes you.
