I bought two - charged up both and hit the water. They never worked. Upon inspection both had water in their housing. The small rubber plug that has to be removed to charge and then replaced had leaked. A small rubber plug isn't good enough to keep the saltwater out. They need to come up with a better design that uses a negative pressure latch.
