I have a couple of Phinacs, but have actually not dropped them yet. My issue with one of them however, is that my anodized endcaps are chipping. Will not be buying anymore of these. Besides this, they are just too expensive.
I mostly have IBTanked as well. I think I'm up to 10 now. I dropped one, attached to a ProVari, and it chipped the paint on the tank a bit. And, this past week, I dropped one on concrete, and it shattered. However, the replacement tube is like $6 ($5 more to paint it), so really I don't care. I will continue to buy these.
