I tried an e cig 2 days ago!

[fabricator4]

Concentrated, I thought it seemed high also but i started at 5% or .5ml in a 10ml bottle....had no taste at all so I kept adding 5% until it had decent taste and that's where i'm at now.

The flavour concentrate strength can vary a lot with the brand, but 30% still seems very high. If it's working for you though...
