I'm also just looking without first hand experience, and still waiting for my nikita clone parallel box. but I would prefer both a small one and if possible, tool-less battery changing, so the dimitri, nikita and cherry-bomber etc is out.
The raptor seems nice but a little big/heavy for my tastes. So, i'm currently thinking about clones of castigador and abbadon. The dos equis is also cool, but i'm just a little uneasy about jd tech only recommending builds down to 0.5ohms... It has however been tested much lower than that by others without issue though...
About clones, then I was also uneasy about them previously and e.g. got authentic kayfuns etc., but after I got my first clone(a velocity rda), then I have completely changed position on this, both because i'm on a tight budget as unemployed currently, and because they are perfectly fine, just check reviews/discussions thoroughly first before buying e.g. on fasttech. My own position is that for me ,clones are fine for rda's and mech mods and such, but not for e.g. regulated mods with real electronics inside. Maybe that dosen't make much sense, but that's just me...
If the products where cheaper I would buy originals, but as they are frequently not, and since the design usually isn't patented, and many times sold out imidiatelly, then I think it's ok to go with clones, but I just wish they weren't 1:1, as i don't support ripping off the owners logo and trademarks... Of course I know that the development process takes time and effort and so the price shouldn't just reflect the materials but also the actual development, but still, I feel the price is ridiculous on many items imho... The mutation x series and e.g. twisted messes is a succes and frequently gotten originally because of the reasonable price imho...
