Hi people, i have buy the RY4 Hangsen 100ml 6mg, Production date 23-10-2015 / Experiation date 22-10-2017 and i have a strong horrible taste with it, i have already tasted the RY 4 Hangsen in 30ml and this is not the same thing, i don't know why but the taste is not sweet at all...

I have try to let the bottle open for one night but always the same strong horrible like chemical taste.
Try to change the coil but same problem.

Do you know what to do with my bottle to correct the flavor ?

Thanks !
