We have an Army member in Afghanistan using a Buzz Classic(the original Buzz) as well as the BuzzPro and his PV's get to see more action than he does, and they are giving him perfect
vaping 24/7. That's about the best test I can think of.
So if the Buzz Classic and the Buzz Pro can earn the Army Soldier seal of approval, they'll work just fine for the rest of us.
As an added plus, they are "Wharfingly Cool".
Let us know of your findings.
