My stainless steel Nemesis clone is from Fasttech, and not from HCigar, I think, but based on my experience and what I've read, there doesn't seem to be a whole lot of difference. Perhaps HCigar has a lower incidence of issues? Mine looks and feels great, aside from the initially crunchy button which is now much better. Mine thankfully came with magnets, not springs, which I did not expect and for am thankful for. One thing of note though: I don't feel it's worth getting into mech mods if you don't use RDAs. I do not yet rebuild, and my fake Nemmy has pretty much been designated as a back up vape, as with a regular Aspire or Kangertech tank on it, you're not getting anything more out of it; better vape on an electronic device.
