If they want to actually sell any they should put a video demonstrating the product on the front page and not limited by being Apple Quicktime only nor hidden behind a "super nanny" logo.

this is great, but it wont save any lives if no one is around or if the kids are expected to be playing in water. There was a death at a day camp in my neighbourhood last year; the kids were under watch, adults were swimming with the kids,but because of all the activity (outing at the pool for day-camps can get really crowded) the life guards did not spot the kid in distress and he drowned. A device like this that inflates when distress is detected would have save that life.

I think it just activates an alarm when it comes into contact with water. It's not a floatation device as far as I can see.
