Product Reviews: �€�I found the O3 technology provided a nice, arm-friendly feel when hitting from the baseline as well as easy access to racquet head speed and a generous sweetspot. You don�t need extremely fast swing to take advantage of it. With an easy swing, it seemed to me there was a nice blend of power and control coming. At net, this was a maneuverable stick. It has good pop and comfort.�€� - Bruce, Corpus Christi, TX
