After finishing my brew, I used to use my drinking mug as the vessel to carry the "dirty" dripper to the kitchen sink immediately, empty the mug, and came back to my coffee. W/ the drip tray, i no longer need to make that extra detour. Once I finished brewing, i just needed to place the "dirty" dripper to the tray next to my scale. Save so much time. It's one of those "mundane" accessory that has so much impact on your workflow.
