Review on Heavy Duty Vortex Shaker With Touch And Continuous Mode - 110V by Kyle Larjin

I hated to use the Robart paint shaker I have for my liquid watercolor paints: time consuming to strap in bottle, loud, slow working and with a bad track record for durability. I have not had this vortex mixer for long, but have been very pleased with how well and easily it works with my Dr. Ph Martin's Hydrus liquid watercolors in one ounce bottles. About 20 seconds to mix even bottles I haven't used in quite a while. I have not put any ball bearings in the bottles as it seems to work fine without them.
