I bought this product last year in February 2018 to use my USB sticks and photo SD cards with the 2017 version of the MacBook Pro as it only has USB-C ports. . . For the first few months it worked as advertised and I was able to use all ports and my USB sticks. Then, in November 2018, I got notifications that "USB accessories are disabled. Turn off accessories that are using too much power to turn USB devices back on." and I was unable to use my USB device or any device other than a laptop USB-C charger. This adapter lets your USB C connectors are completely destroyed and unusable when you want to transfer data, files, photos, etc. to or from your laptop or whatever device you use it with I called Apple Support and it cost me over to fix my computer $300 If I had known this was going to happen I would have just bought an Apple adapter instead of this fake adapter I tried to save some money with Revain and ended up with hundreds of dollars due to damage to it lost my laptop - thanks for nothing, I will no longer trust this seller or any tech devices sold on Amazon.
