I got my Pico about two weeks ago and it's my new favorite thing ever. I am so, so impressed with it. I can't believe how well it works throughout the modes, and the battery life/efficiency is much improved over the 60W. I was using a 2500mah in the 60W and barely getting a few hours from it. 2100mah VTC4 in the Pico lasts most of the day.
Those of you who got the kit: How loose is the AFC on your Melo 3? Mine is crazy, crazy loose. Any way to tighten it? It's not so loose that it's changing up on me while vaping, but almost. Super easy to knock out of place. Otherwise I love the tank, too. It's a great set.
