UPDATE - 9/26/17 - Having used this device for over a month now, I've come to understand its one major quirk. If you want to use an external hard drive (not a USB stick, but an actual external hard drive for backups, for instance), you need to have your power cable connected to this device. It's not enough to have your power cable plugged in another USB Type C port on your laptop. You need to have your power cable plugged into this device. If I do not, my external hard drive will improperly dismount during backups on my Mac OS Sierra. I tried backing up my OS many times (a larger backup...over 2GB) and every time, my external hard drive (Western Digital Passport) would improperly dismount. I finally figured out that it's because this adapter is not providing the needed power supply to keep the external hard drive properly mounted. So, finally, after trying to plug my power cable into this adapter, I found that the external hard drive no longer dismounts. I'm not happy about this because it means that I must always have my power cable with me whenever I want to use my external hard drive, but now I know, and that's something.**********8/12/17 - So far I've tested the micro SD slot and the USB Type C power slot and these work fine. I've also test the USB ports and these work, but there's a problem when using multiple ports. Here's what happens.First, I plugged an external HD into one of the USB ports. Then I plugged in my  Cocopa USB 3.0 External CD Drive, CD/DVD-RW Drive, CD-RW Rewriter Burner Superdrive For High Speed Data Transfer for Laptop Notebook PC Desktop Computer Support Windows/ Vista/7/8.1/10, Mac OSX  and put a disc in it. When it went to mount the disc, the external HD disconnected from the Mac (I'm running OS Sierra 10.12.6) and I got a warning from the OS that the HD was not disconnected properly. I tried this with a powered external HD too and it did the same thing when I loaded a disc into the external DVD player. I also plugged in both of my external HDs at the same time and this happened, but then I tried it again and I was able to get both HDs to stay connected.This unsafe dismounting should not happen. It seems that the device is not able to maintain power/connectivity to the devices that area already connected when a new device gets introduced and mounted. I'm very concerned that this is going to corrupt one of my external HDs one day. Basically, it looks like I'm going to have to play this little game of learning which devices to mount first, when to temporarily dismount a drive, and when it's safe to mount it again.I'm glad to have a device that has all the ports that I need, but I am disappointed with the quality of the engineering for the price. What can you do. It's Chinese. Expensive Chinese, but Chinese nonetheless.

I bought a brand-new, fully-loaded MacBook Pro about a month ago. Before I did, I read tons of reviews with a lot of hand-wringing about "no USB or other data ports onboard". Well, with this, you can ignore all the hand-wringing. (The newest MacBook Pros, as of December 2017, are outstanding, so don't let the "no ports" business stop you.)I've been around the block many times on hubs, on both Windows and Mac, and with reviews here to match. Many disappointments left me skeptical about manufacturer claims. So, as soon as I got this hub, I put it through its paces.By far the best way to do this is a free app called Black Magic Design Speed Test. This reads and writes dummy data to your hard drive (SSD in the case of the MacBook Pro) and gives you a report on the data transfer speeds in both directions. Sure enough, this hub performed as promised, with full USB 3.0 speeds (about 8 times that of USB 2.0 -- I did an A/B test). There was absolutely no difference between USB 3.0 speeds among my suite of other USB 3.0 devices and this hub. Full pass on that.It has just the right combination of other ports too: media cards, Ethernet. I did assume it would NOT also pass through a charge to the MacBook Pro (since many don't) -- but, yes, it does that too. So, when you plug this into one of your four USB-C ports on your MacBook Pro, then plug your charger into an empty USB-C port on this hub, the hub will pass the charge through to your Mac, which leaves the other three USB-C MacBook ports free.And -- guess what? It does all of the above with NO EXTERNAL 120-V POWER SUPPLY. It's self-powered via its USB-C connection to the Mac. One less thing to plug in, carry around, lose, or worry about. Nice!I was kind of shocked not to see this product at the Apple Store online. They only have other really large, clunky, expensive ones but not this. Baffling.You slip this little thing (more or less the size and weight of a deck of cards) into any protective pouch to away keep the dirt lurking in your backpack, and you're all set for just about any situation. Need more USB 3.0 ports? Just plug the  Anker 4-Port USB 3.0 Ultra Slim Data Hub for Macbook, Mac Pro / mini, iMac, Surface Pro, XPS, Notebook PC, USB Flash Drives, Mobile HDD, and More  to this hub, and you've got four more USB 3.0 ports. Need more? Okay, plug in another one of those Anker 4-port hubs.As you use this, you'll notice that it can get very warm, but nothing alarming, and not surprising. Only issue at all, and barely worth mentioning.In my view, this product needs to be better-known, and should be recommended by Apple too. Whoever designed this deserves some recognition.
