This kind of snuck up on me, since I don't often read some of the other topic areas. I have seen these advertised and thought for a minute that they might be fun, but it seem that they are a bit too dangerous for my tastes. Please read before you consider the purchase.
Sorry for the redundant post but I feel this is good information loosly related to "boat accessories" where there is significant traffic on the webboard.
