Keurig B 40 Review

Because it delivers various drinks via K-cups at a substantially hot temperature, the comparison to other makers is distinguishable.  The owner is not obligated to purchase K-cups if the petite filter is purchased for repeated use.  Because it generates heat for the 30 seconds of on-demand hot water, it saves on electricity that way and will also shut itself off if not used in 30 minutes, thus saving the owner the worry of not remembering to do so. The one-cup-at-a-time means there is no burner nor a hot element sitting ready for hours, wasting energy.
