Tried e-Lites a few times. I bought the starter pack and a few tips from the www, but my local corner-shop started selling them about two weeks after that. Personally I don't rate them. The 'smoke' is harsh and tastes slightly antiseptic. I don't think they have much nicotine in them either.
I bought a Vapestick from Tesco Pharmacy and what a difference. Lovely nutty taste and a good hit. However, it ran out after a day as I just kept puffing on it. At £10 it ended up costing more than 20 cigarettes.
I think what most offends me about e-cigs is that they are just as vilified as normal cigarettes in public, so, ultimately pointless.
