I've been using the Smoketech Magneto for about two months now and vaping for a year and a half. Everything was going fine until I picked up the Stillare RDA. I owned the Igo-L, two Igo-W's and a patriot prior to my purchase and everything was fine. I was vaping all of them between .5-.6 ohms (using 30A batteries). Of course I've been using the Stillare exclusively for the past week and loving it. There was a bit of a gap so I adjusted the 510 pin to allow for a flush fit. However, today I had an urge to use my Igo-L (.5 ohms), adjusted the 510 pin back up a bit, and all I got was a nasty burnt cotton taste. It was definitely juice'ed up and not dry. I checked for shorts with my multi-meter and found none. So I proceeded to try my Igo-w's and the patriot, all had the same burnt cotton taste. Checked all for shorts and found none. So, I put the Stillare back on my Magneto and had no problems. I know for a fact that my other RDA's worked perfectly well before I bought the Stillare. Has anyone ever encountered this problem? Sorry for the long winded post and thanks for any help in advanced.
