I know those are frequently confiscated here, but when I vaped, most the equipment was made in China anyway, and the highest quality brands were also from China.
Puff bars are apparently exceedingly popular, but to me it seems like a giant waste, I personally mixed my own juices from pure pharmaceutical quality PG and nicotine, and buying the best vaporizers and tanks from China. But that is next to impossible today, which I suppose is a part of why puff bars have become so popular.
IMO the EU regulation is a bit heavy handed, but I suppose it does prevent extreme use to some extend, personally I’m happy I could use vaping as a means to get rid of my addiction, where several attempts before vaping had failed.
