If you are ok to gamble with your gf's health but not your own, that says a lot...
I, for one, bought a FlowerMate Vapormax V for my gf, but that's because:
1) the kind folks on FC dismantled the device and we are confident it should be safe health-wise
2) she asked for something idiot-proof (which it is)
3) she wanted something with no glass part (after breaking one of our Ascent stems)
Also the FM is an original design by Smiss, a large e-cig maker, here we're talking about a copy-cat found on DHgate... not exactly the same thing...
So I would tell you to buy the new FlowerMate 5S instead of this, it has 3 temp settings, is hassle free, easy to maintain, hits hard and doesn't cost an arm.
