Just returned from HK. Here is the low down on vape there.
Only 2 actual BM vape stores exist. The others are gone. E-Land Vape (Causeway) is full of bad attitude, outdated hardware and stunningly high prices. Not worth the time or trouble to go there.
The other The Vape Shop (Sai Ying) is actually a well equipped shop. Looks and feels like a "real" shop. People are nice and knowledgeable. Big selection of everything. But as seems typical, prices are high. BTW, they didn't have a Proton.
So shopping HK for Vape gear is a wash. Plus HK laws are not kind to vapers. No nic is legal in HK. I brought my own which is acceptable only if for your own consumption.
I understand one can online order nic and mix it into their juice, but if caught, it is the same trying to get narcotics through the mail.
Then there is Shenzhen, mecca for all things vape. But you won;t find anything there. It is all made for export and most shops selling any vape stuff are most likely fake. Buy it, you own it.
So, as always. I wait until I get back to the US on a visit to get my stuff, and at the best prices. I did find one place ave40.com that does have nice stuff and good pricing. Worth a look see. I did order my Proton from them and they actually do ship in mainland China as well. Now waiting for my Proton to arrive.
