I have a Yeti mug and a Keurig K-mini Plus. When I use my mug, there is an oversplash, sometimes to a significant degree. This riser brings my mug closer to the pour spout, reducing the oversplash. The original drip tray fits into this, though you will need to remove the small overhang at the back. This will also fit inside the storage container thing that goes between the drip tray and the spout when you travel with the k-mini plus. Hope this helps someone else out as well.
