I like the pack just fine and I like the idea of Sims washing their clothes and it gives the younger generations chores to do other than put away dirty dishes. But I don't have it in all my households, maybe about 7 households. But I did find that the whole washing/drying process can really piss me off and has caused me to yell at my computer screen sometimes which can be emberrasing. Especially when my Sims go from one hamper and instead of going to the next one and consolidate the dirty clothes into one bag, the Sim puts the 1st load straight into the washing machine and I have to have him go back for the other load. That can be infuriating if the house is several levels and the laundry room is in the basement or the attic.
But I have found a good solution. Hamper(s) go into the laundry room and they will get filled even though the Sims take off their dirty clothes several floors above the room. Then I assign a Sim to do the laundry, usually a teen or a child if they are present. I learned that trick with an apartment complex that had a shared laundryroom because the maid does not work well with laundry and locked doors, even though the doors are set to be open for services like the maid service. If the household is big or an apartment complex I place more than 1 washing machine and dryer. I have x3 washing/dryer combo in one household.
