Do you just want your hair knocked down to one length all over somewhere between 3mm (#1 guard) and 13mm (#4 guard) (1/8 to 1/2 inch in freedom units), then this is the option for you. Its cheaper, its fast and it works. Still finished off with a neck shave and aftershave. No frills all function. Do not under any circumstances pick this if you do not want a single length all over buzz cut. You may not be happy with the outcome.
