I have this fasttech clone...

I like it alot and I think it looks better than a nautilus mini, it's well made and the only minor gripe is that sometimes when you undo the base the coil unscrews from it rather than the chimney. But that's not any bother really, it vapes a lot like a nautilus for obvious reasons but you do have the option for more air flow and because it's shorter you do get a more 'direct' inhale which makes it feel a bit different too. would I pay the price for a genuine, no, but I would recommend this clone if you prefer the look to a nautilus mini, personally I don't get any real noticeable difference in flavour but it does feel a bit different to vape on, I've only ever used 60/40 in it, which was fine.
