Buyer Beware.
Sellers on Aliexpress, eBay, Amazon, or any other marketplace platforms is NOT authorized reseller by [Linlai™ Global] and their tubes were not supplied by [Linlai™ Global]. None of those vendors, including those named themselves such as ‘Linlai Tube Store’ is NOT the Linlai Tube Factory itself. The Linlai Tube Factory does NOT sell directly on any of those platforms. [Linlai™ Global] do not do forensic research on where those online vendors get their supply, if they are authentic Linlai tubes and what quality they are of. If you are tempted by the low price those vendors are offering and the quality claim they make, you will need to direct your question to those vendors and do your own research. [Linlai™ Global] will not endorse or confirm quality of Linlai tubes found in the Chinese domestic market, some of which were resold by unauthorized Chinese vendors to overseas market claiming to be of the same quality as the [Linlai™ Global] tubes. [Linlai™ Global] will NOT respond to inquiries such as ‘is this true and is it identical to your tubes’. Chinese domestic tube market, unfortunately, is very much unregulated with insufficient trademark protection, a very chaotic supply chain dotted by ‘underground or backdoor deals’, sometimes even mixed with counterfeits and bad qualities. We do NOT know all. Our business is to supply quality tubes through our own operation and reseller network. We are not supply chain investigators. Thanks for your understanding.
