Got my $8 Rose V2 from VaporBank yesterday, looked great until I got into the base, there I found some burrs inside the positive post hole and on the little post itself. Dug my good multimeter out and found it was indeed shorting out. Got out my tiny machinist files, took the burrs off everything and now there is enough room between the post and base body and the short is gone. There were some other burrs here and there that I touched up, only issue now is threading the lower tank section onto the base is still gritty. I have some super fine lapping compound that will fix that and make the treading like butter. The rest of the fit and finish is amazing, the upper tank sections fit is perfect, unless you look close you wouldn't see the seams and think it was one solid piece. Also pretty good fit with the plastic tank as well. I'll get the threads lapped tonight then strip it down and into the ultra sonic cleaner to clean her up. I've got to do my research and learn how to build it, looking forward to give this one a try!
Oh, there was one other issue, the rod they sent with it used to tighten or loosen the base is way to small for the hole they drilled in it, the hole measures .176 and the rod is .156 I'll just use a #16 drill bit from one of sets I have but if someone who didn't have these you'd end up deforming that hole with the rod being so much smaller. I guess these issues are why they were dumping these for $8, but once addressed it was a hell of a deal!
