I’ll be honest I started out with vape pens and went to full rebuildable atomizers,drippers and even squonk mods. I guess this is the way the industry has gone. I was sceptical but let me tell you as an experienced vaper these mr fog disposable are great vapes. So far has lasted me 5 days and still going. I’ve ordered 2 more flavours. These are so good for people just coming off cigarettes or for people that want a no hassle vape. There’s no spit back the battery lasts about a day of moderate vaping and they are so tasty. You won’t regret buying these. Happy Vaping
