save your money it is not that great [SEP] this sucks i tested with a polish that had been sitting for a while after all i am capable of giving a few arm shakes of a polish that is already fairly well mixed i bought this specifically for polish that needs some extra help does not do the job it is more quiet than some and has little rubber feet so it does not slide everywhere but still moves a little would not recommend would not purchase again after trying several bottles i donated it so someone else could try it
