So im looking on ebay and ali express.Theres a huge price difference between sellers.Theres cheap on ali express from china described as wuxing under brand. On ebay theres like priced cheap from china.But described as unbranded under brand.Then theres ones on e bay 3 times the price described as wuxing under brand .But still most of those post from china in 20-40 days ,same as the ali express ones and unbranded ebay ones.So how do you tell whats genuine anyone?
