Great for my twins at Disneyland
We used two of these harnesses for my twins in Disneyland, and they were the best decision we made.  They are two and like to run away and hate to hold hands, so it was nice to be able to give them a bit of freedom without losing track of them.  The harnesses are thin so we didn't need to take them off to go on rides.  Multiple people stopped us and asked where we got them.  (For my daughter I wrapped a little red bow headband around one ear to make it a Minnie harness.)  Some reviewers complained of a chemically smell, but ours smelled perfectly normal.
