I broke the glass by accident and I couldn't get it all out. It is jammed up inside and if you're not easy enough, you could bend the flanges inside and break it. I got cut, my friend got cut, people at a shop got cut and there was glass all over the place. There has to be a better design....it took at least an hour to get all of the glass out of the setup. It's nice that the new one pops right back in but I don't want to go through that all over again, ever again.
