The packaging of the cable was very basic and didn't even say anything about Thunderbolt 4 except for a sticker, but the cable meets specs and works perfectly with my Razer Thunderbolt 4 Dock: The Plugging into my Dell 8K display was hassle free and the data transfer rate was top notch in every test. Looks like another solid Anker product. You are paying a premium over the branded price as there are other cables that appear to be the same as this unbranded and unofficial TB4 certification but at half the price so this is something to consider. Will be updated if problems arise
