Works great, take a little time to get the regulator keyed in.  But after that the only trick is to let your keg settle for a couple of days after you bring it home, to reduce the foam.  Or just use a pitcher right away and it will be perfected in a couple of days.

Take your time with putting the tap, hose, Co2 and regulator together, you have to make sure there are no leaks.  I found it is best to go exchange your empty CO2 tank, and work out a deal to buy a bigger one to have, then just use the small one as a back up.
