Let me try to help you here,mine behaves somewhat like a pipe.One suggestion is to stand in front of a mirror,then start to draw very lighty,it doesnt take much for the atomizer in these to fire up,watch the LED and practice very light draws,the lighter the better i found.On mine i take two short draws at times only one,then i can do way long ones with alot of vapor keeping the draw as light as possible.You wont think that it is producing vapor on these light draws but let me tell you omg it does!!!!Really,it is so close to like smoking a pipe,when i smoked a pipe i never took hard draws on them.Try the mirror method,begin with the ligtest draw,just barely draw on it till the LED lights up,is all it takes for mine to kick ....,lol
About a month ago my son and i got two DSE901 starter kits from MiniCigarette.net,these are the real SLB 901's.When we first got them we both had alot of trouble with them,we were hitting them way hard,WRONG!!!!!!.We both thought they where total JUNK!!!!!,,,Well,we were wrong,the batteriy lights would go off blinking like crazy,we cussed swore,thought we got ripped off bigtime.I worked with those 901's,hell,now that i learned to take light draws on them,it is hitting like a million bucks,darn near close to Marians.My son has the platinum 901's from Puresmoker,those i do believe are the RN4075's,those do take a bit more of a draw and are really good.Be patient try the mirror deal,every one of these e-cigs vaporizes differently,small learning curve on these till you get them working for you.
