I've used these before, borrowed from a friend. We were on a boat and my 7 year old got seasick. We put them on and within 20 minutes he was fine. These really do work for us. I see some reviews where they didn't, and the only guess I can make is that, like medication, not everything works for everyone. I like the fact that they're drug-free. I also feed him ginger (both crystalized and pickled) and that works very well for nausea too. The problem with ginger is that its a strong flavor, and a little sharp on the tongue. I happen to have a 7 year old who loves it, but most won't. Also, the ginger is perishable, where I can keep these in my purse or glove box indefinitely. I highly recommend these. And, the shipping was super-fast.
The reason for only 4 stars is: I ordered these for my son, and, from another retailer, the "adult" size for me. They are the exact same size, and the exact same size as my friend's "adult" ones. So, I paid 2 separate shipping charges, for the exact same product. The colors may be "kid friendly" (mine really weren't, though), but the size is the same.
