At first, I was just like you, planning to dig deep in the electronic industry......
after doing some researches.....and searching different suppliers.........all I can conclude was fakes and fakes everywhere.....
Even for real stuff....the profit margin is so little....there were too many competitions expecially if you are located in North America... BestBuy FutureShop Walmart...you name it....
If you really want to get in to the industry.... ignore the suppliers from China; 99% are fakes. Don't waste time searching suppliers in China, search in either EU or U.S.
