My problem with others is the others did not stay centered when stirring. It is as if the magnet inside these stirrers was not centered making them rotate off axis which was OK at low speeds, but would spin out of control at high speeds. This set stays centered at all speeds. Great Set. Review: Just what I needed - Perfect for stirring metallic inks and is just what I needed.
