I bought some for my kids this last Christmas. They adore them. The darned things go everywhere. I think I'm one of the few adults I know that isn't bothered by listening to them all the time.
My husband family lives in a small country town in TN just barely big enough for a wal-mart. He got bored at the family Thanksgiving lunch at Ryan's steakhouse and walked across the street to Wally World. He was back in 30 minutes with a few Black Friday tv's, 2 furbys, an xbox, and a few monster high dolls ;)
