Only had it for a couple of days, i have tried other types that friends have and this is my fave its so easy to change the vape oil, have found them strong though but im sure i will get used to that but i smoke light cigarettes that have 0.5mg of nicotine and the lowest stregth on these is 6mg so i only need a small amount. I added on to the starter kit a pack of black cherry 6mg and they are really nice will def keep using and looking forward to some new flavours!! def recommend they only downside for me is the strength but over all the e-cig is really light to hold and i got the red one and it looks really nice.
