I have the black clone from fasttech.
I would not recommend it in any way at all.
Spring is crap, so I replaced it. The button sparks and gets hot instantly.
I have cleaned it repeatedly, done every fix I have been able to find online, took it to no less than 6 local B&M's, and it still will not work without burning my finger to the bone.
It looks great in my mod stand, and it holds an rba or dripper that I'm not using at the moment wonderfully, but that is all it is good for.
If you get one that actually works let me know. I love the look, the feel, and would love to have one that actually works.
