Good upgrade from a manual ice cream maker. One thing they dont tell you is that although you done need to prechill a bowl or anything like you do with the cheap units, most recipes call for you to mix the ingredients abd then chill them for 1-2 hours. 
Will need to experiment with batch sizes per recipes, the first one we made did not make enough and the second reciped whipped up a bit more overflowing the unit. This was with the same sized recipes!
