Hi, and welcome!
I am new myself, but already figured out that the flavors I thought I would like, well, not so much. I started with the Blu cartomizers. Then did some searching and found out I could refill them so I bought from one of the approved vendors (which I didn't know at the time, but was greatly relieved to see after I found this site) and got the 6 of the 6 ml sample size ones.
They package them in deals like that, and it saves a bit of money that way. I would rather not buy large amounts of ones I might throw away, so thought the small amount would give me a good idea of what I like. Glad I did too, I thought I wanted tobacco or coffee flavored, but they actually threw in another flavor - raspberry green tea - and I found out I like it best of all. Go figure. I like the stronger flavors, like the tobacco or coffee ones, in the morning and when I am wanting a cigarette. As the day progresses, I am using the fruity sweet ones. I seem to be changing flavors as fast as I am charging these stupid Blu batteries.
I am impatiently awaiting my next shipment - so I can decide if I can deal with the 510 I ordered before I knew better. I wish I had been here sooner, would have gotten an Ego twist. My first few weeks of ecigs were with no help from here, just flying solo with the Blu. Then I did some searching and found this wonderful site! So at least you seem to be doing things right the first time. I envy you your Ego!!
