I bought 3 of these attys about a month and a half ago. The first one I bought was absolutely awesome. Vapor production far exceeding any other atty I've used (about 50% more). After that atty died (it lasted a solid month), I wanted to use up my last cisco 306. It lasted about 2 weeks before I broke it (it didn't burn out....I droped my pv and the atty actually broke). This morning, I went to blow out the excess primer from my second hh .357, and a big blob of black nastyness with little black flakes came out the end of it. Totally disgusting. I don't know if the 50/50 PG/VG primer reacted with the steal wool inside the atty, but that would be my guess. This is not acceptable regardless. I cleaned the atty as per manufacturers instructions, and it is drying as we speak, though with the amount of flakes I saw in the blob of primer, the performance will probably be affected. I am going to write an e-mail directly to avid to address these concerns, but I thought I might put it out here to see if they have a public response to this issue.
