Used by Sony Ericsson WTA Tour professional Daniela Hantuchova, the Prince Ozone Seven infuses the O-ports with Carbon Wave Matrix Construction. Some of the benefits include an enhanced sweetspot and more stability, while maintaining the O3 technology of aerodynamics. In keeping with the comfort and maneuverability of the O3 Red, the Ozone Seven adds consistency and stability. We found plenty of control and forgiveness while having plenty of power on reserve for pace and penetrating depth from the baseline. Maneuverability was outstanding at net with a headsize and sweetspot seemingly so large it swallows up volleys and spits them out into the opponents court. The versatility gives the option of punching a hard volley or using the feel in the stringbed for that delicate bleeder, angled just over the net. Serving with the Ozone Seven offers a good combination of power and control. The feel and consistency is there with plenty of access to spin while having plenty of pop for the hard flat one down the "T". This is a nice option for the all-courter at the beginning to intermediate level looking to add some pop to their game.
