I thought I'd post the results of some liquid "experiments" I've performed after recently becoming an e-smoker, in the hope that they may be useful to someone.
I'm using a "super-mini" RN4081; one of these: http://dl.getdropbox.com/u/114752/rn4081.jpg
I purchased a couple of atomizers, as I'd read that they often die after some weeks. I have 2 bottles of liquid; a Pillbox38 "Camel" 36mg and an e-cigs.co.uk generic "tobacco" 11mg.
Now every time I have loaded the e-cig with either Pillbox38's liquid alone, or in 50:50 combo with the generic liquid, everything is fine and I get an enjoyable smoke until it needs a refill. But after loading the first atomizer with ONLY the generic liquid, immediately I experienced the infamous "burning taste" which was very unpleasant!
I thought this was just bad luck, so I swapped the atomizer for my brand new spare one and loaded it with Pillbox38's liquid a few times, and everything was fine. But once again, immediately after loading it with ONLY the generic liquid for the first time, I experienced that "burning taste" again!!! 
The chances of that happening twice on the first load are extremely slim, so I must conclude that in all probability the cheap generic liquid is responsible for ruining my atomizers. I must also conclude that Pillbox38's "totally wicked" liquid is expensive for a very good reason - it will not quickly screw up your atomizer and it really is high quality!
Some other things I've noticed about these liquids, is that Pillbox38's liquid is slightly less "thick" in terms of consistency, and it also produces less smoke (although this may be due to the higher quantity of nicotine in the one I have). The generic liquid seems to be thicker and produces more smoke, but more smoke is not necessarily a good thing in this case!
No I'm not a shill for Pillbox38 or in any way affiliated with him or his companies. I'm just reporting what I have observed with my own eyes in the hope that it will save some of your dead atomizers...
Has anyone else seen similar results to me?
