Well I wasn't happy with the conditions of the valves a the packaging was horrendous, no protection at all, just shoved into a jiffy bag, these things are made of glass, pound on one we're bent, the flimsy boxes that they come were squashed so I expected the worse but lucky they weren't smashed, I straightened the pins and they worked. Why can't you packed them better, only got them from you because Amazon we're going to be delivered on January
