  1. starsHave used the USB and the SD card slot. ...
    5 out of 5


    Have used the USB and the SD card slot. Both work as expected and fast.

    Due to where the device connects to your computer it can sag a little towards the USB connections. However, if it is used on a hard surface this is not an issue as it wont sag below the computer, I used it with my laptop on my lap and my leg was enough to support it.

    Also comes with a rather impressive leather protective case.

  2. Extremely compact

    In particular, the hub is even more indicated when you have a Macbook, because sizes and colors are exactly designed and manufactured to fit the Macbook.

  3. Makes life easy!

  5. Perfect!
    5 out of 5


    I ordered the silver one and the color is also exactly as pictured. It is very small light and handy, fitting into my pocket perfectly.

  6. Durable and helpful.
    5 out of 5


    The build of this type C hub is quite durable and it plugs in well with a stable transfer. My files are easily accessible at a speed that is convenient to me, its not slow at all. I could charge any device while transferring data from a 8GB SD card to my computer.This hub really helps me a lot. Great.

  7. Very good product great for reading SD cards if like me you are a videographer or a photographer this is handy for SD and micro

    Very Happy with it and I think its a very good price for what you get.
    I use mine mainly for the SD card and micro SD card slots and they both work very well this is designed to be on a flat surface and if you have a load of wires with say a hard drive on then it will fall out unless its on a flat surface but any connector would do the same thing as they are only held in by the surface area of the USB-C connector what is smooth itself so as long as you have it flat and your not walking around with things hanging from it then its fine and works as it should and very well.
    Rant over anyone who has a Mac book I would recommend this it comes in a very nice leather holder to protect it while not in use.
    It lines up perfect with a mac book and the grey is a near perfect match and looks as it should belong to the Mac book.
    The micro SD is good for my Action cameras while the SD is good for my main cameras.”

  8. Gold plated connectors for high transfer speeds, compact size, carry much to protect it, overall pleased with the quality.

    “You might find similar adapters like this at a cheaper price but they certainly won’t be built with the same quality as this adapter! The build quality along with the finish is outstanding and matches the quality which you come to expect from Apples own manufactured products . I’m overly impressed with how well this adapter is built and i was also fairly surprised by how compacted it is, i was expecting it to be more bulky but it’s actually fairly small and slimline which is ideal.
    This adapter is compatible with the 2015 MacBooks onwards and it’s also compatible with Windows if you have USB-Type-C like i do on my Windows 10 Desktop, the transfer speeds were good, they pretty much matched the transfer speeds of the built in connectors on my computer.
    The connectors are gold plated which helps to maintain high transfer speeds since gold is a much better connector than copper which most ports use.
    This is a very handy adapter if you have the latest MacBook which only has USB-Type-C connectors, this adapter will allow you to plug Micro SD Cards, Full Size SD Cards and it will also give you back your USB 3.0 ports which are missing from the latest MacBook and the ports are backwards compatible with USB 2.0.
    The adapter also has a USB-Type-C port on which can be used to charge your MacBook.
    This adapter also comes in a nice little carry pouch which is ideal to protect it from becoming scratched when you’re transporting the adapter in your laptop bag.”
