This one I'm excited about... Boge has the new Leo, and they're sending me one to test. It is 800mAh and has some great new design features separating it from all the other eGo/Vgo designs, including a simulated wood grain, cigar tobacco grain, black, cherry red and titanium. It has a large "jewel" on the end, a jeweled end cap to cover the atomizer/cartridge, and built in USB port for charging. It is a true 3.7v unit using a 302 fitting. The cartridges are good for 1500 puffs "6 packs of real cigarettes" they say. At 153mm long and 15mm wide, it's right in the size range of the eGo/Vgo sets offered, yet will pack one heck of a punch at that voltage. This one I'll be writing a review on and doing a blog as soon as it arrives.
