To be honest I found them while searching for Christmas toays and ordered them for my grandchildren to use in the pool this summer. They are beautiful and have a nice weight to them but I have not openned the box much less put the batteries in and put the boat in water.
I was deciding between an RC helicopter, boat, or plane. I went with this one and I must say, BEST PURCHASE EVER!!!!!!!!! It runs GREAT in the pool and it never has filled up with water, or flipped over. Soooooo worth your [$]!!!!!!!
