I've been vaping since January and with a Buzz for @ 2months...I've accumulated a few high end PVs in that time....Every so often I'll pull one out and vape....just to change a flavor...or just for a change all together....That never lasts very long...Nothing else comes close to the Buzz...performance is unmatched and it's durable as well....I find a setting of 4.5 volts and a 3.0 ohm atty to give the best flavor, clouds of vapor and long atty life...If my Buzz was no more I'd order another.....pretty dang quick......
