all overseas travellers must be carefully to purchases anythings in HONG KONG while they are visiting HK. only to purchases valuable things such as electronics products or precious metals jewellery from HK reputable shops, and don't buy anythings from streets stall especially in the night markets of Temple Street,Kowloon, because the stalls hawkers are always cheating overseas travellers by selling them imitation, inferior goods. e.g. a silver accessories stall hosted by a old man always sell silver jewellary at very high price & sometimes sells false & imitation silver jewellery at high price to overseas travellers. Don't buy electrical & electronics products at Temple Streets' Stall and Shops, because they sell inferior and brand imitation products at hight price to overseas customers.
That sounds more dramatic than it actually is. Of course the general street vendor mentality is to extract as much money out of anyone (especially foreigners) as possible however it is not a secret, that they only sell fake products there. In fact it is widely known and even locals go there to buy imitates. Also it's highly uncommon that these vendors will actually lie into your face trying to make you believe it is real. Of course prices vary, but so does quality. Of course the higher quality imitates are more expensive. That has little to do with cheating though, and its still waaay cheaper than the original.
But if you want something that you can return if its broken, something with a warantee and especially electronics, go to a reputable chain store. That also is common knowledge.
yes; I agree with Sebinhk. This sort of thing is not unique to Hong Kong- these street stalls are found everywhere in the world, and especially in Asia. You just need to bring with you some common sense and some bargaining skills.
To expect that something you buy in the street is worth hundreds of dollars is pretty naive, if you want something good quality- go to reputable seller in a shopping mall, or somewhere similar.
If you want something that looks like the real thing but isn't- bargain as best you can at the markets to get the best deal.
