Excellent battery, would easily recommend this to anyone for the value. I use a big battery mod as well, yet I find myself reaching for this if I want a 4v vape. It's allot smarter than the description says- Has a 5 click on, and 5 click off feature, along with a blue led for the switch and a red led for the pass-through port. It also has some sort of mechanism (Causing the button led to blink) which prevents the device from firing if the your atomizer is screwed on too tightly. In addition the threads a very nice and smooth.
