Good build quality
Only 80W (not important for most)
I quite liked the original Tarot. It was a full featured and slim device that had a decent chipset on it (Omni board). The Nano carries on the same good things but in a smaller package.
As far as small and portable pocket mods go, this one is very good! It has a 2500mah Battery in it which lasts quite a while and with 80W of power on tap, it should suit most vapers out there.
Overall, a very good showing from Vaporesso!
