The product is dangerous and ruined my router and router table. Stay away! I couldn't even try it on a piece of wood as within 2 seconds of turning the router on the bit began to flex under the centripetal force of the spinning motor (I've had no problems with the other bits I've had). I quickly turned the engine off, but the bit bent so badly that it caught on the edge of the table, pulling the router off the table it was installed on. It has to be made out of a really cheap material. I didn't pay for the motor and the table but I think I'm lucky the bat didn't do any serious damage to me or my car in that garage.
