Your laptop just got an upgrade
Set name: Dual HDMI Adapter
Switched from a desktop to a laptop for work and missed my dual monitor setup badly. This device fixed that. Easy software install, works exactly as advertised. 10/10 if you need multi-monitor support on a laptop.

Must for laptop users
Set name: Space Gray
I’ve been using this hub with my MacBook Pro, and it’s been a game changer. It has all the ports I need in one compact device, which makes it incredibly convenient whether I’m working at my desk or on the go.
Everything connects smoothly and performs reliably with no lag, no hassle. I connect second monitors mainly as well as external keyboards and mice. The size is perfect too, it’s small enough to toss in a bag or even a pocket without adding annoying bulk.
If you’re looking for a simple, efficient way to expand your MacBook’s connectivity, this hub does exactly what you want without overcomplicating things. So far the durability seems excellent as I have dropped it off the desk several times.

It does what it's supposed to do, except give fluid full screen video.
Set name: Dual HDMI Adapter
It works on a MacBook Neo, but temper your expectations. If you watch a YouTube video with the 3rd screen (and probably 4th screen as well), it's not as fluid as watching it on a 2nd monitor connected to back USB-C port (or via the Neo's internal monitor). This device and the USB-C 2.0 bus are simply not capable of giving you that kind of performance. Also, will need to download and install the driver from the manufacturer's website and allow 2 different permissions for screensharing and to use an updated drive in System Settings.
