The M&R shaker works pretty well... plus it can mix multiple quarts at a time!!
Funny story... I had a 5 gallon of red explode inside of one back in the day (at my old job)... It took forever to clean out... Then (a few months later) for some reason the main shaft sheared in half...?? They never fixed it...
Also... The turnabout won’t do a quart...
The AWT Tornado mixer will supposedly, but I have never tried it..??
