Big advantage to this is probably the cheapest in the market. Unfortunately it is impossible to charge the battery alone, ie the battery should be placed on the handle, so you have to remove the strap, Nunchunk, the handle protective cover and place very carefully for that it loads. After many hours of charging the battery life is very short, I hesitated between the charging station and rechargeable battery ... I regret not taking the batteries. I do not recommend this product!
