this be slightly bigger than the regular controller but it be not a big deal . we use a big screen and play about 10-15 foot away from the tv . the wirless be so great because you do not have to move the GameCube from the shelf and mess with all the cord . there be no lag in response time either . such a great controlller . we try to see how far away we could be when the GameCube would stop receivee signal . we get to the opposite side of the house and it be still work . ha !!
