I wanna ask owners here, does anyone have trouble with the power switch feeling sticky when using? Button does not seem to be at all crisp and almost extremely slow to rebound when using? Got an X70 and came out of the box with the button stuck down, i kept pressing until it worked free however it is never felt anything but sticky/mushy if that is a possible way to describe this lol. Want to see if others have this or not? Thanks big time
