The Nemesis was definitely one of the higher quality mechanical mods, early on. Because of that, it was pretty much cloned by every Chinese manufacturer who dealt with ecigs. You can probably find over a dozen different clones of the Nemesis. Some are better quality than others. One unique thing about Nemesis clones is that there is no such thing as an authentic copper Nemesis. Yet, the copper Nemesis clone is one of the most popular mechs out there.
For those who have an original, you have a beautiful piece of art. If you paid whatever you paid, and you're happy with your purchase, then you did yourself right. For those who opt for a clone, it works well for you, you saved yourself a bunch of money, then you did yourself right. At the end of the day, you are the user. You have to like what you use, otherwise, get something else.
While I don't own a Nemesis anymore, I had a clone and enjoyed it very much. I might get a copper clone again in the future. If they ever produce an authentic copper Nemesis and I find one available, I may be inclined to pick that up instead. I appreciate both and at the end of the days, my bills get paid, my family gets fed nicely, and I have a plan towards my retirement. I think I'm safe to splurge on some vape gear when funds allow for it.
