My wife and I purchased these and, although they are bright and would be fun as props or for a costume, they are not practical for gameplay. It makes the entire apparatus top-heavy and causes arm pain after only a few minutes of play (my wife is a bowler and has fairly good forearm strength already, so it's not just a matter of needing to work out the muscles). If the Wiimote had been placed in the middle, allowing for the batteries to add weight at the back of the hilt, this would be a much more useable toy.
