I have to say they smell so good already that's its hard to believe they will improve with time, but I'm trying to be patient!
juice smells can be decieving sometimes. I remember getting some creme brulee from ENjuice which smelled absolutely gorgeous, just like creme brulee, but when i vaped it all i got was a slight hint of curry! Unfortunately the longer i left it to steep the curry flavour got stronger. A lot of vendors now sell pre-steeped
juice, and if they are mixing to order generally let you know or say on the website if they recommend you steep it for a while.
You can get a non-rebuildable dripper from most vendors too - no need to change coils or anything and they work nicely. I used one for a couple of months and kept swapping flavours with no problems. The 306 ones seem to be a bit better although i am not sure why and they cost anything from £2 - £5 so good value too if you dont want to start building coils, etc.
