I've used it and if it is just about ready to restock it will instantly do it. Kinda nice if you only have a few minutes to play. I have 6 families and now that they are in their 3rd and 4th generation I basically have them just making money so it takes me about 1/2 hour to go through all the games for maintenance unless I have a new family and then I have to feed and baby boost and all that fun stuff so they can have a baby
