I have tried a few of the other e-cigarettes and have been disappointed with them and have gone back to normal cigarettes My daughter had a Vype and on her recommendation I ordered one. I really didn't expect it to be any different to the others. It arrived within 2 days of ordering. Well, I set it up, put in a cap and off I went. WOW! I love it! There are two different settings for the amount of puff you need. It is the best one I've tried. I particularly like the way to change a flavour all you need to do is unscrew the one in it and screw in another. No messing about with liquids that spill and drip, not to mention having to clean the tank to be able to put in a new flavour. Its so clean, quick and easy to do. My favourite ones are Cherry and Mint. I believe that Vype is the best e-cigarette on the market.
