Just a heads up these magnetic stirbars are junk.. idk if it ruined my extraction but i started to notice a film starting on the surface while stirring and the stirbar lost all of its plastic coating.. not thrilled ???? and to top them off.. the little cross isnt balanced at all and scares me running it and the bigger star, i believe is mostly plastic cuz it dont spin in anything but a splash of water...

Yeah i really only bought it for the cross and star but they both leave alot more to be desired. Im still speechless an dumbfounded about the plastic coating on them not being made for chemicals.. They are made an marketed for lab and organic chemistry..
