This is an add on special for busy people….let's say you don't have the time or inclination to do about a minute of internet research or even click through a link on this very website to determine which La Pavoni set you need….Millenium or Pre Millennium (always the question). Let's say that you can't be bothered to remove the group and look under the shower screen to see which rebuild kit you need…well, don't bother!!! Just add this slackerversal add on to the PRE MILLENIUM kit and you are covered. No worries. Whichever machine you have you can get it fixed and have some cool parts left over!
