So here are my general experiences with TheSmokeSafe.com. Most of the suppliers I've ordered from have had spectacular customer service, but James at thesmokesafe.com has set himself apart from the rest.
One of the e-cigar atomizers he sent me ended up killing itself within a week (nasty burnt-rubber taste and the LED wouldn't turn on). I'm sure it was a manufacturing problem and not his fault. I contacted him, and he got back to me within 24 hours letting me know he would send me a brand new atomizer tube ASAP. What really set James apart though is the fact that he called me up and personally asked me which color atomizer tube I would like and whether or not I "would mind" if he included a free 15ml trial bottle of his new RY4 juice. Of course I didn't mind!
So the new atomizer and juice came in, and I was pleasantly surprised to find that he had included a pre-paid envelope so that I could mail him the dead atomizer back at absolutely no cost to me.
His products are also top-notch. The e-cigar atomizer initially had that "factory taste," but I vaped through it within a couple of days (I'd say that I'm only a light-medium e-smoker, so it'll probably go away for most people within a day). After that, vapor production and taste only got better with time. The LED also changes color from blue to yellow once that battery gets low, a feature which I haven't seen on any other e-cigar. His RY4 juice is super smooth, and all of his products got to me in California from Montana within 2 days. To top it all off, his prices are very competitive - in fact, I haven't seen any quality parts for cheaper elsewhere.
I'm not affiliated with James in anyway - I'm just a very very satisfied customer. He doesn't quite have everything in stock yet, but I highly recommend him if you're looking for parts or juice.
