"I have been using vip vanilla and strawberry cartomisers for 12 months and was initially very happy with the products. They went out of stock for about 2 months which was distressing. I have since ordered 2 batches of vanilla and they are sub standard. Many of the refills are duds and do not work- no pop initially and no smoke. When they do work they run out ridiculously quickly- I now use 4 a day when 1 used to last me over a day. The strawberry have never come back into stock and were removed from the site recently, despite customer services telling me several times they would be back in stock in a couple of weeks 3 months ago. You need to change your supplier"
