There are several issues I have with the design.  1. the individual brew section requires the use of a plastic insert to hold a K-cup. That insert does not work with our re-fillable K-cup containers. 2. The supplied re-fillable K cup container is awkward to use.  Big bulbous plastic container holds the filter. When you use it, you must first remove the other K-cup insert.  3. The reservoir is simply way too large and it ONLY supplies water to the single serve side..it does not feed both sides. When you want a pot of coffee you have to pour water into the top of that side of the unit. 4. Single Serve brew time is slow..much slower then a Keurig unit.  5. The display has no dimmer setting..the light is so bright that at night it lights up our kitchen.  SUMMARY - it does the job but for the money I would have expected something better
