Ive noticed sometimes the ps vita can get a little uncomfortable to hold, makes my hands ache or the unit slips .. im thinking my hands are abit bigger than the unit was designed for. So i found this sony vita silicone case and was wondering if anyone else had tried one of these yet and had any feedback? The case also appears to cover the touch pad on the back so Im unclear if this effects it? Or if anyone has found an alternative product that resolves big hands let me know! thanks.
