Review on INTLLAB Function Vortexer: Revolutionizing Adhesives Centrifugation in Lab & Scientific Research by Stephen Johnson

Purchased to help mix my Vallejo acrylic miniature paints. This works for thinner colors and washes, but doesn't mix well with thicker colors. As others have noted, the engine is finicky and not consistent. Sometimes it works well, sometimes it falters or works very slowly. The lid is also useful for mixing paint with the cap down, but mixing right side up is awkward and difficult to keep the bottle on the mixer. I understand this is a funnel made for lab samples and designed for use with thinner solutions and cultures, so you may be fine as long as you use it as intended. I gave it 3 stars because of the motor mismatch, but the rating itself is for miniature model artists who might also consider it.
