Was looking for a specific mod, the vaping 101 team were really helpful, quick correspondence through email and fast shipping could not ask for more. As for the Gaur 21, great mod. Large but not as big as some make out plus for a dual 21700 it's light. Feels solid in the hand thanks to the fibreglass reinforced poly carbonate frame and the resin inlay on the blue is beautiful. No battery or button rattle and the Vandy chip is excellent. Only negative is no customisation on the tcr value that I could find.
