HP 28C/S battery doors


Hello, does anyone have experience that the battery door on the 28C is more sturdy and less susceptible to break than the door on the 28S? They are designed the same, but I have noticed the plastic is not the same shade of brown, so is it possible one is more sturdy (to hold the door in place without degradation) than another?
