My Buzz Classic has lost it's mind! I noticed my usual vape was a lot hotter and harsher than normal so I got my meter out and the crazy thing was reading 8 volts! Tested the batts and both read 4.1 fresh off the charger but put a different set in anyway. Buzz then metered 4.5, put my tank back on and first vape was hot again. Took the tank off, metered 8 volts again. Turned the pot screw down, tested and it metered 8.3?!?! Is my first born Buzz Classic kicking the bucket?
