Well, the not crashing thing got me concerned..mostly because I've read the DHB is notorious for crashing. So, I ordered some as a comparison from another source. All the vials in that order were crashed. I pinned twice out of Pristine's, no PIP, and twice out of the other source, terrible PIP and a reaction on top of that. So, I really can't give a good opinion yet. I can't pin the other source's because it literraly fucks me up with every pin. The not crashing thing has me sctratching my head a little.
