content: Well, now we are a little leery about replacing, but we have invested in about 5 boxes of K-cups (taking advantage of sales at Kohl's) soo..this is going back to Costco tomorrow. We read the reviews but thought that the newer models had replaced the older ones-guess not. We had been using bottled water entire time so we knew in 2 months it wasn't a build up issue. It's short-cupping and going back.
