I bought to replace my outdated and started to crumble logitech f710. At first, it was very unusual: the left stick is located, and the right one is below, not on the same level, but now I don’t notice it anymore. Very good responsiveness of the sticks, much more accurate than Logitech had. As for the batteries, I don’t know any problems, because I use batteries. There is no button to turn off the gamepad, it turns itself off after a sufficiently long time
