I've tried a few of these e-cigs now, from elites to gamuchi.... Awful things, poor vaporisers and capacity. However I now gave the Titan e-cig a go and that's awesome, actually fills your mouth, nice and heavy puffs unlike the elites etc... refillable cartridge too! However I found the flavoured e-juices are awesome and its more effective than the glade wall plug in. However I do find vanilla tastes so yummy I probably smoke more capacity than I did in real cigarettes, but its still miles cheaper just ordering e-juices in and refilling the Titan especially when you mix the nicotine % to your liking and the flavours, YUM!
