I love my pebble. ❤ I am(was) a heavy chain smoker, I gave up and bought a Vype 3 weeks ago, I have not smoked 1 cigarette since. I actually prefer the 18mg Wild berries to real cigarettes this has amazed me and I am delighted to have stopped smoking. Please watch Vype UK website though, quite pricey. I bought over £70 worth of cartridges and a starter kit direct from manufacturer. Only to find out it is nearly 30% cheaper at Argos!! Not only the refill cartridge but even the starter kit. Vype £17.99 plus postage, Argos £14.38. Refills Argos £24 for 12 Vype £30 plus delivery. I will be popping to Argos from now on!. The pebble is a great idea. Give it a try, you will Love it!.
