If they are good quality clones then you should be fine, let's underline "good quality", based on the price, and coloring schema..it sounds like
fasttech or Ebay. I would get the manufacture name of the maker and google it and see if they are any issues that you might have to deal with. I know on Patriot clones...they are some misalignment between the air holes and
coils...you also might have to drill air holes on the patriots little bigger.
On the Nemesis, you'll probably need a magnet kit for your firing button. The clone Nemesis tends to have poor made spring, so upgrade that spring or get "good" magnet kit for your firing switch.
I'm not big fan anything colored unless it was done properly...issues of voltage drops in mechs and other worries of poorly colored RDA that can contain lead,
