After what I initially thought was a bad Dekang e-liquid order from fasttech.com, the liquids I ordered eventually steeped to a very good vape that I now like to order more of. I would like to try the Hangsen brand, but fasttech has two different brands: the regular Hangsen and the Hangsen "Crentia" brand. The Crentia is about double the price of the regular Hangsen, at about $4 for a 10ml bottle, shipping included. Does anyone have any experience to share on the difference between the two?
