  1. starsHigh Speed
    5 out of 5

    :

    The connectors are gold-plated, which helps to maintain high transfer speeds since gold is a much better connector than copper that most ports use.

  2. All functions works as it should.
    5 out of 5

    :

    It comes elegantly presented,as it is made of aluminum in silver, very well finished and extremely light.Quality is fine! All ports work excellently as it should.

  3. Exceptionally Smart, Sleek and Works Perfectly - Great Item
    5 out of 5

    :

    This clever little device comes very professionally packaged in a nice strong box inside of which you get the Hub, a soft carry pouch and a good set of instructions. The build standard is exceptional with a solid Aluminium chassis and lovely curves to neatly complement my sons MacBook. Having said that I wanted it for my Lenovo Yoga Tab 3 Plus which also supports USB Type-C.
    For those not familiar with USB Type-C, it allows for two-way power, so apart from charging the peripheral device a peripheral device could also charge a host device. This means you can do away with power adapters and USB cables, and have a single strong and small solution that works for all devices.
    This Hub slides nicely into the USB-C port on your device and makes a satisfyingly secure attachment. I would not want to be moving it around too much whilst in use but sitting on a flat desk next to your Mac it works well. Your own Type-C cable then plugs into the “DC In” of the Hub and this allows a throughput of the power to continue charging your Mac whilst at the same time powering the Hub. The end result is one cable and a seamless connection instead off two cables and two separate units. As the Spice Girls said, “Two become one”. Add to this the fact that it is quite a demur little beastie at only 3.3 x 0.33 inches (that’s less than 8 ½ x 3 x 1 cm) and it really does connect up like a small growth on your machine as opposed to a whooping great monster sitting next to it.
    In terms of functionality it is quite obvious what it provides. You started with just a pretty mundane and single function USB Type-C port on the side of your machine and once hooked up you now have an SD and Micro-SD card slot for all your cameras etc., and also 2 x USB 3.0 ports providing data and power links as well as all the other joys of USB 3.0.
    Don’s get me wrong; the Hub is by no means perfect. Just because you have all these additional ports doesn’t mean you can plug in everything under the sun. The whole shebang does have a 1.5 Amp and 30 Watt load limit so think again if you want to charge your car battery whilst running your fridge and boiling your kettle from your MacBook. It will however, charge your average phone and allow various dongles etc., to be connected up quite happily. If I had one criticism about the configuration of the ports it would be that I can see no need for over complicating things by having an SD and a Micro-SD card port. Everyone I know possesses an SD to Micro-SD card converter so why not save manufacturing costs and just have an SD card port?
    All things considered, and despite my minor criticisms, I think this is a very neat and functional accessory. In an era with an ever-growing demand for multitudes of accessory ports on our computers, this does a great job of meeting some of that demand. Given the slender and sleek design and portability of this Hub, combined with a solid build quality I find myself compelled to be very impressed with it and I can thoroughly recommend it.”

  4. Fits perfectly in my new Macbook Pro.

    :

    Very handy and completely cool.Fits perfectly in my new Macbook Pro and the product is very well built. I’m very pleased.

  5. A well built USB-C hub that performs well makes it a great match Macbooks
    5 out of 5

    :

    “Dimensions: 84 x 34 x 9mm
    Weight: 27 grams
    I love the compact size of this USB-C hub. It looks smart and has a quality aluminium metal exterior.
    The hub has been designed well to pair with Macbooks.
    I like how it includes a USB-C socket to allow you to connect the power alongside using the extra connectivity.
    This is especially useful for the Macbook 12″” which only has a single USB-C socket as its only IO port.
    It will give the Macbook 12″” similar ports to my 5 year old Macbook Air 13″”. I have been reluctant to upgrade to the newer Macbooks because of the lack of connectivity. As a travelholic and photographer, I rely on the SD card slot and USB 3.0 for connecting a portable SSD to backup my pictures.
    The performance of this USB-C supports full USB 3.1 bandwidth. The SD Card slot allowed me to read at 95MB/s and write at 70MB/s with a Sandisk Extreme SD card which is specced at 90MB/s.”

  6. such like connecting my external hard drive or SD card reader
    5 out of 5

    :

    “Since Apple introduced the new MacBook’s with only one type C port I was facing some issues with my new laptop, such like connecting my external hard drive or SD card reader. Due these featured being really important and essential regarding my job, I was looking for a solution for this problem. After I’ve done a research and reading many reviews online, I decided to buy this GN21B Type-C Hub Sold by Egolggo UK. It came in a luxury black box with heat-sealed plastic around, to make sure never been opened so its 100% new item. Inside I found my new Type C hub nicely fitted in a sponge cradle to protect from any scratch or damage. User manual was also included, well written, easy and understandable language even for not too tech-savvy people, full with illustration about how to use it.
    The hub itself is made from aluminium, same as the MacBook, stunning built from quality materials, it feels like it’s part of the apple product family, but way cheaper then a similar gadget from the Apple Store.
    It took me a few days actually to realise that there is a small velvet bag under the sponge cradle in the box. With this awesome gadget now I can connect my SD card or external HDD even while I’m simultaneously charging too my MacBook.
    Didn’t require any setup whatsoever; worked properly right away, when I took out of the box. There is five port located on this HUB to serve all your needs; One Type C (DC IN) for charging the laptop, Two high speed 3.0 USB port, one SD and also one micro SD card reader. I had no speed transfer issues since I’m using this, not even when playing back a 4K video from a flash drive.
    I’m really happy with this GN21B Type-C Hub, saved me so much headache of how to connect my regular USB data gadgets to my new MacBook. Now I can connect my old style printer too, which has not featured with wireless connection, only USB. Well worth the money I paid for it. It is also compatible with my wife’s Dell and my daughter Chromebook too. If you are looking for a well designed, multipurpose, and highly portable USB Type C hub then this is the one you need!”

  7. The perfect partner for any new MacBook computer
    5 out of 5

    :

    The perfect partner for any new MacBook computer. Connects up without any drivers or software. Simply Plug and Play! I carry this in my bag all the time and use it several times a day as a professional photographer. Its fast, easy to use, and a great price. What more do you want?!

  8. Pleasing to the eye
    5 out of 5

    :

    “This hub perfectly matches the colour of my MacBook. The single connection to the USB-C port is secure enough that I don’t think it will cause any accidental disconnects.
    The material and manufacturing quality are first class; you could quite easily pass it off as something Apple would make.
    For an informal test, I connected an external SSD Drive to one of the hub’s USB 3.0 ports then transferred a 19GB folder. It completed the task in about forty seconds. I then directly connected the SSD drive to the MacBook’s USB-C port and ran the test again. Exact same time to transfer the same folder. This, informally, tells me that the hub is not bottlenecking the hard drive’s throughput to the laptop.
    I then transferred 8GB of data from an SD card and found it to be as quick as the same transfer done using the built-in SD slot on my 15″” MacBook Pro Retina. The hub’s SD card reader works just fine.
    As long as this hub proves reliable in the long term, I am perfectly happy. You couldn’t possibly make it any smaller, lighter, or more aesthetically pleasing.”
