Review of RY4 Double Flavor-TFA:

don't believe the hype, or if u do, get a sweetener or perhaps a different flavor to pair with this. notes of caramel are non-existent. the smell seems to hold all the caramel. after 2 week steep stil only tasting tobacco. but with that in mind, it's a very pleasant tobbaco. that is why my rating is middle of the road. does not seem to matter the percentage, no Carmel or sweetness is detected. take all reviews with a grain of salt tho, everyone's flavor detection is different, everyone's tongue is different. the tobbaco tho as it is, quite enjoyable not to harsh or overwhelming and not holding that nasty artificial chemical taste some products have. this was my first time ordering, using and reviewing a product on this site. 
the store itself, awesome. purely. fastest shipping I've ever experienced of any online purchase in my existence. will be buying and reviewing more soon.
