I have a bunch of CE2 ceramics and I love that I can make a pile of wicks and coils and use them interchangeably on my Killer, Divers, and Terminator. I'm not sure why Todd had so much trouble in this area. I did take a chip out of the installed ceramic trying to get it off the post and I did have to sand the pin in order to fit replacements. I imagine that SmokTech would prefer that you purchase their replacement units.
I have a bunch of cheap DCT tanks and tips like the ones that come with the Terminator and don't use them, but for a $10 item, who can complain? The material is cheap and the tank is wobbly, but I haven't had any bad hits or problems with connectivity like Todd (and I have the juice control all the way open).
I personally have no regrets about what I've invested in my other atomizers and I think the Terminator is a much cheaper mass produced lower quality ripoff, but SmokTech did a good job copying it and I've had nothing but great vaping with mine. I figured that I would just pack it away or throw it away if it sucked, but it doesn't. For $10 I would definitely encourage the uninitiated tank cartomizer vapers who are unlikely to shell out a wad of money on an unfamiliar Greek website to try one.
