Thanks for the info and prompt response. I've been holding mine like a pipe, cupping the base (just trying to separate it from cig smoking more and more as I go) so covering the carb hasn't been a problem. I'd say it's about the same in terms of force of draw required as my wife's. Sometimes it feels like I have to pull harder.
To be honest, the more I am using it the more I am having different little problems with it. My wife's (albeit used much less frequently than mine has been) is just churning along and gives consistent smoke output throughout a cartridge, etc, etc. Mine gets to be real weak in the throat hit and amount of vapor very easily. I can remedy that in short term with my newly acquired juice by keeping the atty coil primed and the cart freshly topped off.
Just a bit disconcerting the noticeable differences in performance between mine and the wifey's. I can deal with it to a point as I recognize the qc may not be great on these things and there will be some variance. But, I'm also trying to determine if my atty might be a bit of a dud before my 14 day warranty expires

Sadly, the company I purchased from was great during the order and shipping. But, I've not had any response to my queries over several days.
Maybe I'll just pick up a new 901 atty from somewhere else. Need to have a couple extras anyways... Just got in "cheap" to start and now that I'm finding it's working out well for me (the vaping thing)... anyways... getting a bit rambly
thanks again. anyone recommend a good place to pick up genuine 901 atty's for good prices? or places where I know I'm getting the real thing and average price for them?
later,
Jason
