UPTab Mini DisplayPort to Dual HDMI 4K@60Hz Adapter Multi-Stream Transport (MST) Hub, DP to 2X HDMI 2.0

Ok so this device works well. Certain with Windows you can create three extended screen no problem. Caveats. 1. It does come with (and needs) a USB power supply so be sure you have a USB port open for the power. 2. Along with that many computers come with at least one "Always-On" USB port. That works better because if your screens time out and the computer powers down the USB port the splitter it's plugged into, the HDMIs will disengage. My solution is to just put the computer to sleep if I'm not using it. Truly though the product does work reliably

Two months later no longer works.

This product does not work with early 2014 MacBook Air mini display port. My laptop is almost 10 years old so it could be my graphics driver? Not sure. Just be sure it will work with your set up before purchasing.

MacOS High Sierra 10.13.6 will only mirror external displays/TV's. I thought this would extend to multiple displays but I guess I didn't read all the details at the bottom of the page when they should have been at the top. Will be returning but still rated 3 stars.

Was simple to setup. Works great

Ok so originally I thought it didn't work but it turns out I'm just a moron.

It does not actually work. It's a fraudulent product.
