Battery life is listed for the lowest setting, I believe. It's probably exactly true, but only under perfect circumstances. This is standard in any industry. Things like using a higher heat setting, turning off and turning back on, etc, can cause the device to work harder than it needs to. 1.5 hours is far more generous of a real world use than I was expecting. It's kind of like when they say your car gets 32mpg highway. You CAN get it, but you probably won't every time.
My alfa got "early delivery" so instead of friday as I was sadly expecting, it arrives tomorrow! I'm so happy. It's an NYE miracle, and you better believe I'll be using it while out at festivities.
More mouthpieces would be cool, but the one included seems so versatile and compact. What would you change or want?
