I purchased this dual purpose Cuisinart to replace my single cup Hamilton Beach for the rare times I need to make a full pot of coffee. I previously also owned several generations of the Keurig. So...I thought this was the perfect choice to eliminate having several appliances on the counter. Well I Loved it until it started to leak all over the counter from the single cup side. I thought at first I hadn't secured the water reservoir properly but after several checks this was not the case. Also went to Cuisinart's website for troubleshooting, faq's and submitted a inquiry regarding the issue...to no avail, didn't even get a response. I have read other reviews and I agree the single serve side DOES spit all over.. I did not have an issue with KCup but I used the included kcup. I haven't had a chance see how it works with other kcups or ground coffee in the single serve side, as I have been using tea bags for one cup at a time. The water reservoir will still have AT least another 8-10 oz left when the ADD Water comes on..so it seems I have to refill it more than I should. I have had other Cuisinart products most recent, that were lacking in quality control. Disappointed to say the least for the money...My inexpensive Hamilton Beach gets five stars.
