Mine showed up this morning and it's got issues. Looks like I'll be contacting the Ebay seller for a refund. Hopefully he'll be cool about it.
Issues:
Air flow cutout on one side is jacked, other side is fine.
Threading is really rough and full of trash.
I could probably deal with those two if it weren't for the positive post threading being all f'd up. Can't screw down the hex head screw enough to capture a lead.
Also, the screws in the bottom which hold the negative posts come loose on their own, causing the negative posts to spin. These would have to be hit with some loctite. It was also full of machine oil and other various debris, including some dirty cotton strands. Overall, this thing is a POS.
This is the box it came in. I'd avoid these if you see them. Not sure who makes this clone but it's not very good. FWIW, has the Sub Ohm Innovation logo, "Made in the USA", and a bogus serial number on the bottom.
Grand Vapor Station has a pre-order in place for the second run of authentic BDs. There are about 11 slots left. I may jump in for an authentic... or I may just get a Pontus. A little gun shy about wasting more time on another crappy clone.
