Actually amazing hub, it just works!
Color: Space grey
This dock is carrying my handheld system so hard right now, and for such a good price. I have literally every port filled including using the HDMI and it hasn't failed on me at all.

Good little device
Color: Space grey
Nice little device. Works well with external drives and HDMI connections to a MacBook Air.
Doesn't work great with a mouse USB 2 donegal - sporadic.
Does work with USB 2 keyboard and a monitor HDMI for creating a "docking station" for my MacBook, but difficult with no mouse option.
Good quality. Fairly compact. Nice color! Decent value for money for a known brand.

No annoying "Disk not ejected properly" messages!
Color: Space grey
I use these with MacBook Airs, both Intel and Apple M3, and they stay connected. Previous —cheaper—dongles kept disconnecting with no apparent moving of the computer or the dongle. I'd get the annoying "Disk not ejected properly" message repeatedly, meaning I'd have to remove the dongle plug, reinsert it, and hope that the external device showed up on the computer and stayed connected.
These always stay connected and seem to work well for the external devices I use.
I think it's in the plug: with the Acer, I hear a distinct little click when the plug is fully inserted—perhaps some subtle locking mechanism the cheaper dongles did not have.

Instantly addressed a defective unit
Color: Space grey
2nd EDIT: Not only did the company offer a refund, they also generously shipped me another unit, and it works just as it should! They gave fast responses when the first unit gave me issues, and addressed it as well as you possibly could. I would use them any time!
EDIT: the company quickly reached out and offered a full refund as a result of a faulty product. For me, that goes a long way. I have plenty of ACER products and normally have no issues with them. could have just been a faulty single product.
Very bummed. For the first 2 hours of use it worked great. When it’s just USB-C to HDMI connected it works fine, but the second I go to plug my Mac in, while using the HDMI to stream to my monitor, the screen begins flashing every second or two on both my Mac, and the monitor. The flashing screen is happening at the same time the Mac keeps making its “chime” that the charger is connected, over and over again. Clearly something is going on that the charging is not staying active. whenever the charger is first connected it causes a quick(ish)black screen, which I could live with if it just happened right as I plugged the charger in… but when the charger KEEPS thinkings it’s just getting plugged in over and over, and keeps flashing, it kind of makes the product useless. And I’ve already thrown the box away so I guess I’m stuck with a product that doesn’t work. Super bummer.
