This product was a gift and I tested everything. Its such an awesome gamepad at this price.
1.Design eregonomic is goodand built quality is decent though its a rrplica of x box 360 controller.
2.All buttons are strong enough but click noise is there. Analong sticks are smooth and I suggested you all to wear a THUMB GRIP over it to prevent wear of cap.
3.Vibration is fantasticone which is decent and natural.AB and XY back light helps in dark.
4.Playtime is good with good backup. Wireless connection too good.
