Hello. I recently ordered 3 bottles of "Hangda" e-liquid. I am trying to find a new, affordable RY4 similar to Dekang RY4/DK4. The website I was shopping on had pictures of the bottles, they clearly say Hangda. The item description also said Hangda. The order confirmation email - "Hangda." Now I see my shipping email - and they all say Hangsen. I'm disappointed because I've already tried the Hangsen RY4, I was trying to buy a Different brand. Just venting I guess. I might contact the vendor, not sure if it's worth it.
