This has been working great for mixing paints, glaze medium, washes, varnish, etc. for miniatures (Army Painter dropper bottles, Vallejo dropper bottles, and Citadel pots). The pad on top comfortably takes either the tip or butt of a dropper bottle, and I appreciate that it's pressure-activated, so I can use it with one hand. The results drop off once you start getting into larger volumes (e.g., a 1.75oz bottle of Testors Dullcote), so consider something more heavy-duty if you're working with larger bottles of paint, but for the typical small bottles, it's a great, inexpensive vortex mixer.
