yeah i've got one, its great for fluid changes as its quick, but you say you want your 4pots spot on- there is NO better way then a mate in the car pumping the pedal
pedal down-open nipple close nipple-pedal up
pedal down-open nipple close nipple-pedal up
and carry on - basically you only ever want the nipple open when the pedal is down, if you have it open when the pedal is up it sucks air back in the system.
even using the bleeder i always use that method a few times after just to get the air out.
