these are great PVs so there is definitely something wrong... the other suggestions above are a great start for the parts you currently have. i have a riva, ego, regular 510s and the advice i could give you is get some Cartomizers sometime. the atty method just didnt work for me in terms of consistency, coming apart, etc... for those new to ecigs, cartos are the way to go. i've had several friends get ego/rivas with cartos and they like them much better than the attys they came with.
