They are with my 11 year old yes. I wouldn't say it's the first thing that pops into his mind while thinking about the money burning a hole in his pocket but if he walks by one at the store he will probably buy it.
I feel yeah but he gets a dollar a week per year he's been alive. Usually blows through it real fast, gets a little uncomfortable for me when he's between interests and the cumulative total gets up there....
I got a pack of tech decks and passed them out to a couple of my buddies this Christmas and I was shocked at how overjoyed they were. 10/10 highly recommend.
