I agree with everyone who has mentioned the build quality and the center post screw issue. Also, one of the two Acerig clones I purchased from Simple Vaper, had one of the negative gold plated posts stripped out as well as the post hole being un drilled. The issue with the center post screw holes is basically that they are the incorrect screws. I too, used the screws from a Stillaire as someone else mentioned, because they matched up perfectly.
Someone mentioned we should be understanding because we bought a "clone" and only paid $20 something, and I call bull.....$23 may not seem like much, but I actually bought two so now I'm up to about $50 close to half the price of the real deal. Even though I usually stick to authentics, especially when it comes to mods, I've gotten a few clones now, in Vapebox and in trades and stuff, and some of my RDA's especially are 1:1, and excellent quality. I'm not going to lower my standards, it's not like they were given out, I had to wait weeks for it and some people are paying even double for the same crappy quality on these. It's when companies are held to a higher standard that they will raise the bar. For those of us who waited on the pre-order, we would have gladly waited an extra week or so for better quality I'm sure, or most of us anyways. I think from now on though I'll stick to buying the real thing, used or at a discount, unless I know for sure what the quality is of a clone before purchasing. I've still heard mixed things though on whether the authentic is worth it, or has issues as well.
On a positive note, I'll say it has better flavor then even my Atomic, and Helios, my two best attys out of things like the Stillaire and the new Zenith. Even with authentics I'm getting tired of having to wait for the 2 and 3 versions for a quality product. It would be one thing if these manufacturers were offering them at a discount to previous versions purchasers, but most don't unfortunately. Don't get caught up in the hype, and unfortunately I did this time, and IMHO,this one, the 1st run Acerig, is mostly just hype! I'll be getting rid of at least one of mine, once I find some screws to go with it that work. I had to use some from my other working RDA's just to be able to test it!
