Last week I ordered for the second time a 30 ML of Custom China RY4 18mg.It tasted absolutly fabulous.Best tasting and sweetest RY4 I got from madvapes in a long time.Vaped my way thru the bottle in less than a week.So i ordered another bottle,ths time the big 60ml,18mg.filled up a carto and definitly not the ssame tasty liquid i had a week prior.I was kinda disapointed because I was expecting to have a nice big bottle to last a while.This bottle seems almost unflavored,or weak in flavor.Hoog,Is there a different mix or batch here? The 30 ml was so good!! maybe the 60 was sittin around awhile? does it need to steep?
