Welcome, Duncan. I'm a newbie, too.I'm trying to find the best ecig for my needs, too.
Hi Melissa, Welcome!
I started with the DSE901 and didnt get much vape (was a very heavy smoker) - I got the Riva 901 with the Low Resistance atomiser (reccomended to me by Abe at Liberty Flights) and I love it! You'll get lots of reccomendations on here I bet and it's all about finding what works for you, just remember everyone is different and there is a MASSIVE difference between using prefilled cartridges and filling your own with diy juice. I'm using DIY juice now and I love it, I can get massive clouds of strawberry vape or little clouds of harsh nicotine throat hit, depending on my mood.
Love to everyone
Duncan
