The different beater attachments are nice to have but not a necessity. There is a plus etched into the bottom of the mixer that singleton beaters like the whip and blending rod and the double beaters, standard beaters and dough hooks, the beater with the notch should be clicked into. The standard beaters have no center shaft so that what is being mixed sheds off instead of being trapped in the center of the beater. The mixer has been made sleeker over the yrs. to make it easier to wipe clean. The head of the mixer is heavier than the back to reduce hand fatigue and "pull" the beaters down into the bowl. Lastly, the motor is DC instead of AC , more expensive type that allows for the distinctively different speeds. Cord is a heavy duty fused round cord not a flimsier split cord.
