Great deal, and much cheaper buying the 4 pack instead of buying each camera individually.  Also way better to buy them in advance, because buying a waterproof camera while you're on a boat is very expensive.  I found the camera easy to use, especially since another reviewer noted that you won't really hear or feel that a picture was taken... but the strap stayed on just fine and I got some nice pictures while snorkeling the great barrier reef.
