The Infinity Pro has OUTSTANDING battery life. Outstanding in as much as a hard core vaper would likely not require a battery change but once a day. That is incredible. This has always ben a problem with any
vaping devices. My beta test of the Infinity Pro produced excellent battery life and the ability of the
device to handle a multitude of atomizer types and resistances.
I understand the Buzz Pro shares the same circuitry as the Infinity Pro. In this case, pick your form factor. They will both perform way beyond your expectations.
