Just got my new Vamo SS from
fasttech
The 510 threading is def weak and I could tell it needs TLC. Unless I screw them down really tight (which I've read is a bad idea), they don't fit very tight.
The ego threading seems perfect, however.
Don't forget, the vamo is a cheap Chinese product. Sure, they sell the
mod for $60 USD, but in China, they make money selling the same mod, plus two 16500's, plus a charger AND shipping for less - so obviously it's CHEAP. I'm not knocking it because I love the fact that I can get all that for such a cheap price, but it ain't perfect.
