Yeah, the carto tanks do bring it up to a new notch

My daily use setup is a black and brass Buzz Pro with an M1A1 tank and shorty stainless steel drip tip.
I'm a fairly senior engineer at a large, conservative, corporation. I started vaping at work immediately after stopping smoking. I'm supposed to be able to interpret corporate policies, ours is pretty clear that it's aimed at burning tobacco, so I didn't even ask my manager (that would have forced him to go uphill to HR, giving people a chance to say "no" out of ignorance).
I vape in my office all the time, and at internal staff meetings, don't do so during client meetings. I'll vape in the halls, though not on manufacturing floors. My peers all know what it is, and other than kidding from people I've known for over 15 years (honest jokes), I haven't heard a peep from anyone. It probably doesn't hurt that my all-day vape smells a bit like vanilla custard
I'll also vape out in the wild, in stores and at restaurants. I'm not trying to be "flashy" about it, not exaggerated or blowing huge clouds of vapor, just treating it as an acceptable, legal, thing to do. On the extremely rare occasions where I get a question, I explain what it is, a personal vaporizer that replaces an old smoking habit.
