I just got the Infinity from notcigs and I am beta testing it. This thing is amazing. The batteries it comes with are on par with the CR123A that comes with the buzz. It's much smaller and lighter. Feels great in your hand (thats what she said). Vapes perfect. The VV on this is perfect it has a scale with numbers on it so you will always know where your sweet spot it. Feels great at 3.7 volts feels great at 6 volts. Has not blown an atomizer. Plumes of vapor. This is a must have for any vaper. Check out the price only $80 and $110 with batteries and a charger. Cheaper than most mods. I have to say this is hands down the best mod I have ever owned. It's a thing of beauty.
