#1 Does the reservoir function to fill the single serve, or do you have to pour water in each time you use it to make a cup?
The Cuisinart features two separate reservoirs — one to brew a full pot of coffee & one for a single-serve cup. The two reservoirs mean that when you brew a pot, you aren’t using up all of the water from the single-serve reservoir — which is a plus. However both reservoirs are somewhat difficult to access. To answer your question, you don’t have to pour water in each time for the single-serve function, which is an improvement over some other dual coffee makers (like the Hamilton Flex Brew). The single-serve reservoir holds 40 oz — enough to brew three 10 oz cups or five 6 oz cups before refilling. (It requires a limited amount of water to remain in the reservoir to work properly.) For a larger reservoir, consider the Keurig K-Duo Plus, which features a 60-63 oz single reservoir.
