I have used the practice makes perfect a few times as well as the eyes. I plan on doing the kleptomaniac aspiration as well but haven't done so yet. I plan to have my supersim tackle this aspiration together with the aspirations of the latest packs.
I don't think I will use the other items in the list. Definitely not the tattoo because I don't like the design.
The items I have used the most from events are the pillows, mini fridge and trash can from the first event and the game console and framed TV from the Christmas event. Nothing special or new gameplay but I like the look of those items.
