It's my understanding that FT also sells the real deal - just make sure the page says "genuine."
Had my SVD for only a couple months now, and love it. I personally find the multi button easier to navigate than the one button style. Being able to lock the settings is a great feature, even if it does take 5 seconds.
I do find that I have to take off the top collar for MT3S and the similar shaped metal clad AROs, but T3S and Evod go right through. Not a big deal.
Hard to say about vape time, lots of variables. But I find that with a 2900 mAh 19650, at my vape rate, I can pretty much count on two days. And it's easy to pocket another battery (in suitable container, of course), although if I'm going out for the day, I'll usually just pop in a fresh one and not bother.
Seems really solid and well made, glad I got it.
