great 510 battery works with standard 510 vape cartridgesthe instructions indicate that in order to change the voltage (gears) you quick press the buttonbut that is not the caseif you want to change to voltageclick the button 3 timesI love the digital display and the clouds this makesi often purchase cheap sub 10 dollar pens from gastations and always regret it this is worth 15-20 its solid and reliable

Took some time to arrive, but it works great.Longer with a larger diameter than a standard vape battery.
