Been looking thru the forums and haven't found much talk on this, maybe I didn't look hard enough. Really like the smaller size boxes like castigadors or similar, but I really dunno what's good and what isn't. Not something I can do right now, but I'm kinda curious to see folks preferences. I'm still not 100% sure on series v parallel what the differences really are. Id be looking at clones and not wanting to spend any more than I have to. I have an unused set of vtc3 batteries that are needing a home, and I do like the vape I get on my I just 2 battery so I figured I'd look for a true mechanical. Any thoughts from y'all would be great. I watch reviews all the time, but to me they don't really touch on durability and I ain't buying no authentic.
