Coming from the Inkmaster brand 'vort x' mixer (the other cheaper end one on Amazon) this thing is incredible.The stir plate actually spins on the center so it's effortless to position various shaped bottles.I use it for mixing hobby paint. Dropper bottles, ge pots, even Testors square jars. All see a vortex in the bottle. I was actually impressed at how well it worked on the Testors.Even old separated metallics whipped back to perfectly mixed.The push control feels solid and responsive, and you can feel the torque.I really don't have anything bad to say about this.It also has a dedicated power supply, nota generic USB power supply your own brick style, so bonus there.
