Hi guys Am using the EPen as a device to help stop smoking. Have been using for approx 6 weeks with good outcome. Not much info on your site in reference to nicotine value of refills or cigarettes but have found some useful advice elsewhere so no big deal. The battery life isn't brilliant so have bought 2 pens so I have one fully charged constantly. The other comment Is the lack of flavours. I don't intend to 'Vape' long term, but if I did I could be an issue, also there's only one strength reinforcing that this is a alternative to smoking rather than a 'giving up' aid. I think the EPen is an product excellent and Does the job and I intend to continue to use rather than swap to another product. It's professionally marketed and the company reflect this. Your online sales are excellent value and save one a significant amount of money in refills. Thanks for the chance to give some feedback Best wishes Lez Thompson
