I've had my first one for a week.Still using the first clearomizer.The charge lasts 2-3 days,and it still has a great draw and flavor. I ordered and allready have my second one.It does not seem to be pulse modulated like the v8. On the v8,anything above 3.3v it tasted burned and would blow out the coil on around 5v. This one you can set at 4.2 and it 's like a regular battery right off the charger. It seems to out put this all the way to cut off. It does not give you the ohms,The output slide button on the bottom is about 1/64" too long but it still sits up ok. It's built solid and seems to be real quality. I really like the draw and taste,hope Eric will decide to stock them.It's allmost exactly like vaping the c3.
